Paper Abstract

Preliminary results of our investigations of Software Defined Noise Radar are presented; namely, results on the design and implementation of FPGA-based Noise Radar with digital generation of random signal and coherent reception of radar returns. Parallelization of computations in FPGA enabled realization of algorithm in time domain for evaluation of the cross-correlations, comparable with the frequency-domain algorithm in efficiency. Moreover, implementation of relay-type correlator algorithm enabled realizing of the cross-correlation algorithm which might operate much faster. We present comparison of performance and limitations of different considered designs. Digital correlator has been implemented in the Altera/Stratix evaluation board having 1 million gates and up to 300 MHz clock frequency. We also realized a software defined CW noise radar on the basis of RVI Development Board from ICTP M-LAB.
