METHODS AND THEORETICAL MODELLING

SESSION

1/2

• Establish a unified theoretical basis for CP Pol-InSAR, in the same spirit as the founding basis for (quad-pol) Pol-InSAR;

• “Require” multi-PI objective quantitative comparisons of CP vs MP, DP, and FP for all Super Sites, including open availability of in situ data;

• Work system-engineering analyses of CP issues (e.g., required dynamic range, impact of imperfect transmit polarization, SNR, cross-talk, ambiguity levels vis-à-vis H&V quadpol, etc.).

•Extend the texture model to the polarimetric case, which by implication means that a significantly different texture parameter should obtain for each polarimetric channel.

•Develop model-based decomposition schemes for application-specific physics (biomass + topography for example).

SAR INTERFEROMETRY

(POL-INSAR) SESSION

1/2

• The consensus was that scatterometer experiments like the P-band TropiSCAT experiments coupled with modeling are answering many of the issues needed to understand and characterize temporal decorrelation. It was suggested that a similar experiment at L-band would be desired.

• Recent work in mitigating temporal decorrelation is interesting, however the community felt that this work is still in its nascent stages and much work still be remains in this area.

• Consequently, controlled experiments are desirable, but there seems to be no immediate consensus what these could be.

• Applications, like biomass estimation, still require additional studies to determine when compact pol can be effectively substituted for full polarization measurements. Should consider compact pol observables in their own right without a priori biasing with respect to full polarimetric analog measurements.

POLARIMETRIC

SAR INTERFEROMETRY

(POL-INSAR) SESSION

2/2

• One tool the community thought would be very useful is a tool that will automatically co-register stacks of data either in the radar slant plane or data that has been geo-coded.. This tool needs to work at a fraction of pixel and should be not sensor specific.

• The idea of supersites with commensurate ground truth, airborne and spaceborne data was suggested. Examples included Marc Simard’ website and ESA data sets for campaigns like TropiSAR.

• Specifics and how this could be realized in a more uniform and systematic fashion need to be developed if this is ever to come to fruition.

• Another (similar) idea mentioned is to establish one or few standard data sets for comparing the performance of competing algorithms on a common base. Such data could serve as a long-term reference for evaluating new approaches (compare: “Lena” image in image processing)

Two additional supersites for P- and L- band (BorealScat in Sweden, and AfriSAR in Gabon). All data free and open.

SAR INTERFEROMETRY

(POL-INSAR):

FOREST SESSION

•Temporal decorrelation the key limitation factor in the implementation of traditional tomographic techniques: We need to understand better the mechanisms behind.

• Coherence Tomography (based on Single-pass interferograms) is a very promising way to avoid temporal / propagation disturbances;

• The interpretation of SAR tomograms is not established:

Structure Validation Protocol > 3D ground measurements is required for future tomographic experiments;

There is no established way today how to process time series of Pol-InSAR Data;

Data fusion (in terms of Frequency (Optical), Statistical Parameters as texture, Radiometry) may increase stability / performance of Pol-InSAR Algorithms.

•There is a need of an ESA Pol-InSAR mission !

POLARIMETRY, DINSAR & PSI

SESSION

1/2

• Distributed targets play an important role in DInSAR & PSI as they help to improve the estimation accuracy of subsidence phenomena.

• The capability of polarimetry to discriminate targets could get a great gain in DInSAR if properly used.

• Coherence may be not the figure-of-merit to be maximized. More research is needed.

• Polarimetry is useful as it allows to increase the density of PS, separate targets and resolve confusions and better retrieval of orbital errors.

• A careful separation of interferometric and polarimetric aspects in the signal needs to be considered.

• Polarimetric optimization plays an important role on increasing the density of PS with high coherence and lower phase std. dev., but it must be demonstrated that it is not obtained at the expense of introducing biases.

POLARIMETRY, DINSAR & PSI

SESSION

2/2

• There is a clear lack of a PolSAR dataset dedicated to DInSAR&PSI with simultaneous ground-truth. A possible solution is to have proper simulation tools and strategies.

• Additional criteria should be defined specially regarding the accuracy of the quantitative estimation of the subsidence phenomena.

• In case of Sentinel 1, dual-polarization data is better than single polarization data as the former achieve larger PS density. HV or VH channels are important in urban environments as they contain multiple scattering information. Nevertheless, attention must be paid to the scattered power in HV or VH with respect to the noise floor. This should be low to make possible the use of HV or VH.

• Temporal studies are important to be able to study and to characterize the dynamics of the scene.

See “Sentinel-1 Mission Status” presentation at POLINSAR 2015



POLARIMETRY AND

TOMOGRAPHY SESSION

• LIDAR measurements help interpretation of the results, but they should not be taken as the reference against which to compare TomSAR, since LIDAR and Radar vertical profiles are intrinsically different objects.

• TomSAR products should be discussed based on the added-value associated with the applications

• TomSAR algorithms operating in practical conditions (few baselines, lower resolution, temporal decorrelation) should be tested against high resolution TomSAR products obtained in optimal conditions (many baselines flown on the same day), rather than against LIDAR.

• Accordingly, the audience expresses the need for dedicated airborne or ground based TomSAR campaigns, aimed at producing high resolution 3D reconstructions of forest scattering in selected areas where accurate in-situ measurements are available.

• It is also recommended to further study theoretical modeling and performance bounds

APPLICATIONS ON OCEAN & CRYOSPHERE

SESSION

•Although in the long term, it is desirable to have more polarimetric SAR missions, at the present state-of-art the scientific community agrees that virtual constellation combining different frequency and polarimetric modes can be of scientific and operational interest.

•The scientific community agrees that full polarimetric SAR measurements contain more information to be extracted and are suitable to several applications.

•The scientific community welcomes the forthcoming polarimetric SAR missions, and their application to ocean and cryosphere, such as CosmoSkyMed second generation, TerraSAR second generation, ALOS-Palsar 2, RCM constellation, RISAT-1 and the Chinese SAR constellation.

•Moving to operational outcomes it is desirable to enhance the swath coverage, i.e. revisit time (particularly critical when dynamic physical processes must be monitored) by using the most appropriate technology.

APPLICATIONS ON OCEAN POLLUTION

MONITORING & TARGET

DETECTION SESSION

• Further developments are devoted to:

a) algorithms/models for oil detection in ice infested areas; b) finer characterization of oil properties.

• Scientific community underlines the importance for oil slick observation to ensure an high SNR even for the cross-pol channel.

• PolSAR missions are needed to make the oil spill observation scientific idea operational. The most important drawback is the lack of spatial/time coverage. A technological solution that combines the advantages of polSAR and enhances the spatial/temporal coverage is provided by the forthcoming SAR missions operating the CP mode.

• The integration of single-pol measurements and polSAR ones is important operationally.

APPLICATIONS OF SAR

POLARIMETRY ON LAND:

AGRICULTURE, URBAN,

ARCHAEOLOGY SESSION

Agriculture

• There is no competition between time series and polarimetry, but complementariness. One can serve to solve the ambiguities of the others. Recommendation: to continue on this line (time+polarimetry) for agriculture applications.

• Rice monitoring: tests with ScanSAR dual-pol data (wide swath) of Radarsat-2 are convenient. It is an important application, attending to food security reasons.

Urban

• Additional effort in e.m. modeling is needed to understand complex scenarios

• Fusion with other data and sensors should be studied

Archeology

• Polarimetry can contribute in the detection or identification of linear/long features much better than other techniques.

• Added value for end-users: to be assessed.

Key area of SAR Remote Sensing is developing (e.g. Sentinel-1, Radarsat-2, TerraSAR-X, TanDEM-X results)

APPLICATIONS OF SAR


SOIL MOISTURE AND WETLANDS

SESSION

1/3

• For surface moisture and wetland studies a wide range of polarisation analysis techniques (such as coherent decompositions, signature analysis and optimization approaches) should be considered by the community rather than just few ICTD techniques which may not be best suited to some applications.

• It was noted that such wide diversity of tools does already exist in software such as Polsarpro but the applications community should be encouraged to make much wider use of them

• Such approaches require both full quadpol data and low noise floor (HV of low S/N) and hence impact on system requirements for future SAR systems.

• There is also a strong seasonal (spring to fall under no snow conditions) coverage requirement which may not be met by future satellite missions

• It is strongly requested to allow adaptation of quadpol mode availability to suit seasonal requirements for subarctic and boreal wetland monitoring.

Wetland characterization is done with RadarSAT-2 and TerraSAR-X/TanDEM-X Soil Moisture could be done potentially with ALOS-2

ESA POLINSAR-BIOMASS 2015 Workshops



APPLICATIONS OF SAR



SESSION

2/3

• It is strongly wished that L-band ALOS-2 planned mode coverage would permit polarimetric acquisitions over subarctic and boreal region from the spring run off (June-July) to the fall (October) for the operational monitoring of subarctic and Boreal peatland transformation.

• We saw here some evidence that the volume models available are not yet robust enough for operational applications and more research is required to find better improved models for use in decompositions.

• Further R&D is required to see if the dual-receive polarization measurements completed with one transmitted polarization (CP) can generate like HV accurate soil moisture estimation under vegetation cover.

• Among the RH, RV, RR, and RL, RL looks to be the most promising for soil moisture estimation. Others validations are needed in preparation of the upcoming Canadian constellation (RCM) that will include 3 satellite equipped with scanSAR compact.

APPLICATIONS OF SAR



SESSION

3/3

• Cal-Val requirement on the Compact: RH-RV: 0.5 dB in radiometry and phase within 15°

• The Compact will become operational with the upcoming Canadian constellation the RCM. The wide swath mode (up to 350km) should lead to the operational use of polarization information for optimum soil moisture mentoring. Potential barrier : NESZ=-17 dB

• TerraSAR: Experimental polarimetric Mode: HV needs to be calibrated (-25dB contamination by HH and VV)

• Recommend the design of the new mission with low noise floor (-34 dB) and high antenna isolation (-30 dB) for accurate single, dual (HH-HV, VVVH & Compact) and quad-pol polarization information extraction.
