The paper designs a system for radar receiver off-line fault detection simulation training. The system uses embedded micro- processor as the control center of the system, combining with the large scale integrated circuit FPGA and high frequency processing circuit, can generate simulated radar IF echo signal and the modulation signal, and make the radar receiver of each module work in the simulation en vironment, in order to carry on fault detection analysis and training conveniently. The system has been applied in the radar experiment cen- ter, which has improved the efficiency and quality of radar fault detection traininl~.
