Introduction

Purpose

Radar Signals Images Movement Targets

Input

• NS-3– Collect & Record radar raw data (.rpc)

• Radar Toolbox– Convert raw data to frames matrices (.mat)– Save matrices as images (.png )

• Radar Tracking Software– Save matrices in temporary memory

Input

• Radar data matrix

• Radar Toolbox

• Modified Radar Toolbox

Process

Simple Algorithms• Flip / Rotate• Zoom / Crop• Filter– Average– Median– Threshold– Morphological

Complex Algorithms• Detect– Logical Operators

• Track• Plot• Trail• Forecast• Display frames

Output

• Moving target at constant speedFrame 4Frame 7

Output

• Moving target at constant speed– Plot– Trail– Predict

Output

• Target with accelerating speedFrame 5Frame 8

Output

• Target with accelerating speed– Plot– Trail– Predict

Software

• Some automatic functionality• Some algorithms as modules• User intervention• Real images: Code needs debugging• Test images: success

Are new targets within acceptable

variation from old?

Future Work

• Improve algorithms for real radar data:– Noise removal– Predicting– Faster + more efficient, real-time

• Implement seamless integration of all algorithms• Allow user interference during processing• Selection of area of interest• Integration with parallel systems

Conclusions

• Currently depending on Radar Toolbox for importing raw data

• Implementation using MATLAB– Image Processing

Toolbox– GUIDE

• Improvements needed• Radar Tracking

Software developed– Various algorithms

implemented• Track• Trail• Predict/Forecast
