Abstract:

Target simulation both speeds up project development and reduces the costs in radar development and production.In this paper,the method of radar target simulation based on FPGA is studied and the hardware platform is built with the Virtex6 series chips of the Xilinx Company as the core.The system is capable of realtime simulation of the point target echo and adaptation to complex modulation waveforms.System performance is tested by pulse compression methods combing the authentication with chirp signals,and the radar echo information is analyzed.Simulation results show that at a theoretical distance of 1 200 m and a lower latency of 8 μs,the actual distance error is only 11 m with a delay time error of 0.07 μs,within the allowable range in this project.
