摘　　要：为满足连续波雷达任务联试、设备功能检查和人员跟踪训练需要,设计了具有闭环跟踪的动态目标模拟器。根据目标理论弹道和天线角度,完成信号幅度、多普勒频率和初始相位的精确估计,采用FPGA+DSP构架实现动态目标的射频和差信号产生。经试验验证,该模拟器产生的信号经过接收机解调后送至伺服,驱动天线电轴始终对准目标,实现动态目标的闭环跟踪。To meet the requirement of united test, functional verification and operational training of CW radar, a dynamic target simulator with closed loop is developed. The voltage, Doppler frequency and phase of signal are accurately determined by the trajectory and azimuth, elevation of the antenna. FPGA ＋ DSP structure is adopted to generate the RF sum-diff signal. Finally, the experiment for this simulator is evaluated. The signal generated by simulator is transferred to servo after demodulated, and drives the antenna aimed at the target. The closed loop tracking is realized.
