FPGA based random waveform generators for noise radars

The results on the use of arbitrary waveform generators that are based on FPGA technology for generation of complex signals in modern noise radars are presented. On the basis of these devices we propose a radar scheme with digital generation of noise waveforms for both sounding signal and reference and analog processing (stepped-delay method for noise radar). Experimental testing shows efficiency of FPGA-based application in radar with variety of sounding waveforms.
