摘　　要：常规双/多基地雷达在收站和发站之间采用一定的物理链路进行同步,但如果收站或发站在运动平台上就不能建立这样的通信链路,即构成非合作的多基地雷达。讨论线性调频中断连续波(FMICW)在非合作的多基地高频地波雷达中的应用;介绍非合作的多基地高频地波雷达的时间同步问题和对目标回波信号的数字解调问题;通过对回波信号模拟及其处理过程的建模仿真,验证了该方法的有效性。In conventional bi - station/multi - station radar,the synchronization can be implemented through a physical link between the receiver and the transmitter. This kind of communication link can＇t be spanned if either transmitter or receiver is located on a moving flat. The kind of non - cooperative multi - station radar system is presented in this paper. This paper discusses time synchronization and digital demodulations of target echo of non - cooperative multi - static High - Frequency Ground Wave Radar （HFGWR） ,applying Frequency Mmodulated Interruptive Continuous Wave （FMICW） signal. The simulation results prove that the scheme is feasible and effective.
