Abstract

Aimed at improving the detecting ability of spaceborne microwave radar system on the week target, a window function should be added when processing the LFM signals at the cost of SNR loss and mainlobe spreading. To solve this problem, transmitting NLFM signal in the radar signal generator is a better solution. In this paper, we propose a spaceborne NLFM signal design principle, and give the simulation result. And then the hardware implementation using Xilinx Zynq Ultrascale+RFSoC device is introduced. Finally, the test result is given with the Chebyshev window, which the PSLR result is better than -46dB.
