| 摘 要： | 双基地雷达的杂波在距离维上不平稳,距离模糊将对检测性能造成很大影响。空天混合双基地雷达的发射机放置在卫星上,接收机采用无人机。建立了该模式下的杂波等距离环模型,发现距离模糊受双基地几何关系的影响很大,会随检测角度发生变化。提出了减小距离模糊的双基地配置方法,同时也计算了不产生距离模糊所允许的最大脉冲重频。

| Abstract: | In bistatic radar system, as clutter is non-stationary in range dimension, range ambiguous clutter will degrade detection performance greatly. Hybrid bistatic space based radar(HB-SBR), which is composed of a transmitter on satellite and a receiver on airplane, can reduces the transmitter power.Range ambiguity of HB-SBR is different from that of monostatic and bistatic airplane radar.It is dependent on bistatic geometry and detection angle greatly and it can be alleviated by proper bistatic configuration. Maximum pulse repetition frequency to avoid range ambiguity is also calculated and discussed. |
