Real-Time Signal Generator for Noise Radar

Abstract

We present a real-time intermediate frequency noise radar signal generator that provides pseudo-random signals with uniform, normal, exponential, and Rayleigh probability distributions. In addition, normally distributed samples with uniform power spectral distribution with arbitrary bandwidths can be generated. The noise signal generator is implemented and tested on a Xilinx Ultrascale+ RFSoC FPGA based development board with the aim of testing the effect of distributions on target detection performance of the noise radar. The generator can also be used as a baseband signal source and an environment for noise radar waveform design.
