Design of RVD radar if signal simualtor based on FPGA

摘要

Spacecraft rendezvous and docking (RVD) is one of the major tasks in space flight mission. This study discusses an approach for simulating the intermediate frequency (IF) signals which the RVD radar received based on the principle of direct digital synthesizer (DDS). The velocity, distance simulation and noise generator are presented respectively. The whole simulation system was implemented on the platform of field-programmable gate array (FPGA).
