Design of Radar Signal Simulator Based on the CPCI Bus

Radar signal simulator play a key role in radar debugging, performance evaluation and equipment maintenance. The large bandwidth, high power transmitter is always a hot research area in radar signal. The radar signal simulator used as the signal source, can generate multi-channel arbitrary waveform by software programming which can meet the requirement of real-time signal output. With the development of integrated circuit, the work clock of FPGA improve constantly, FPGA combined with DA can be used to produce any broadband signal. This paper introduces a design scheme of radar signal source by combining FPGA with four DAC chips of 1.6GHz sampling rate, using industrial CPCI bus structure makes the system more versatility, compatibility and scalability.
