DESIGN AND IMPLEMENTATION OF AN ENHANCED RADAR SIGNAL PROCESSOR
Ibrahim Mohamed Ali Metwally;
Abstract
Key Words: Moving Target Detector (MTD), Fast Fourier Transform (FFT), Wigner Ville distribution (WVD), Field Programmable Gate Array (FPGA), and Receiver Operating Characteristic (ROC).
Summary:
In the present thesis, a sinusoidal detection method based on WVD is applied in MTD for realizing a bank of Doppler filters instead of the direct FFT or WVD in a typical ground based radar. The proposed MTD scheme, designated as MTD-SWVD, does not suffer from cross terms produced due to the bilinear nature of WVD. It enhances the target detection capabilities by providing higher detection probabilities and additional gain in the improvement factor, in the presence of ground and weather clutter, compared to WVD and direct FFT schemes. The performance evaluation of these schemes through the ROC, which measures the detection probability versus the false alarm probability at different values of SNR, is presented. Also, a hardware implementation, analysis of the proposed MTD-SWVD using FPGAs is introduced.
Acknowledgment
First and foremost, thanks ALLAH the most gracious the most merciful for giving me the power to finish this thesis, I wish to express my gratitude to my supervisors Prof. Dr. Mohamed Riad Al-Ghonaimi, Dr. Fathy Abdel Kader, Dr. Mohamed Refky Amin, for their encouragement, guidance and support from the initial step to the final.
I also would like to express my Special thanks to Dr. Fathy Abdel Kader for his continuous encouragement and useful notes, through all thesis phases.
I also would like to thank my friends Eng.Assem Mustafa and Eng.Hussain kafafy who used to give me fresh ideas and support at the time of obstacles.
In addition, I am heartily thankful to my mother, my wife, my daughters, and my brothers for supporting me and giving me the time to finish this thesis. Someday I will find a way to make it up to each one helped me.
Finally, hope that my work will have your satisfaction and acceptance.
