Moving target detection for frequency agility radar by sparse reconstruction

Frequency agilityradar, with randomly varied carrier frequency from pulse to pulse, exhibits superior performance compared to the conventional fixed carrier frequency pulse-Dopplerradar against theelectromagnetic interference. A novel moving target detection (MTD) method is proposed for the estimation of the target ’s velocity of frequency agilityradar based on pulses within acoherent processing interval by using sparse reconstruction. Hardware implementation of orthogonal matching pursuit algorithm is executed on Xilinx Virtex-7 Field Programmable Gata Array (FPGA) to perform sparse optimization. Finally, a series of experiments are performed to evaluate the performance of proposed MTD method for frequency agilityradar systems.
