Design of the radar real-time simulation system joined with hardware

To improve the real-time property for typical Pulse Doppler radar simulation, an idea of signal-level simulation using hardware was proposed. The system framework and information flow was studied, then a host method of moving target echo simulation was given. Most of all, radar signal processing was realized by FPGA, which includes digital quadrature detection with IF sampling, pulse compression based on LFM, moving target detection with FFT filter, and cell average CFAR function modules. Finally, the target distance and velocity was achieved. The technology discussed could be used for single-radar precise simulation and electronic warfare simulation of multi-radars.
