摘　　要：为了提高无源雷达系统的测速精度,研究了基于多普勒频差的速度测量。利用典型航线的仿真试验结果表明,相比传统的位置差分测速,基于多普勒频差测速性能有较大提高。同时,给出四站时差系统的测速精度理论推导,并且仿真分析Y型布站时,不同多普勒频差测量误差情况下的速度精度分布规律。仿真结果为无源雷达系统设计和应用提供了理论依据。To improve the velocity accuracy of passive radar system, frequency differences of arrival （FDOA） technology is presen- ted. Simulation results of typical flight course show that velocity accuracy can be greatly improved based on FDOA camparing with traditional method. Meanwhile, theorectic analysis of velocity accuracy of four stations time differences of arrival （TDOA） system is given, and distribution discipline is simulated at different FDOA error for Y shape. The simulation results provide the theory ba- sis for the design and use of passive radar system.
