对双基地雷达系统的同步方式进行了研究与改进, 提出利用GPS秒脉冲时间信息将发射机同步信号参数化的方法, 接收机通过参数重构同步信号进行回波信号的接收处理。该方法避免了从直达波中获取信息, 也提高了发射机的共享性, 使任何一部接收机都可共用一部发射机。通过对导航雷达JMA2254的实验, 实现了无直达波雷达参数重构, 达到了预期的实验效果。

The synchronous mode of bistatic radar system is studied, and a method is proposed to parameterize the transmitter synchronization signal by using the GPS second pulse time information.The receiver can receive the echo signal by the reconstructed synchronization signal with the parameters.This method avoids obtaining information from the direct wave, and can improve the sharing of the transmitter, thus any one of the receivers can share the same transmitter.Through experiments to navigation radar JMA2254, radar parameter reconstruction with no direct wave is realized,which achieve the desired experimental results.
