摘　　要：分析了双基地雷达目标回波的概率密度分布与接收角的关系 ,并推导了发射机工作在电扫和机械扫描方式下的双基地雷达天线方向图损失公式。对不同的双基地几何配置条件下的双基地天线方向图损失曲线进行了仿真。仿真结果显示 ,双基地雷达的天线方向图损失比单基地的要小。The relationship between probability density distribution (PDF) of the target echo of bistatic radar (BR) and receiving angle is analyzed in this paper. And the antenna pattern loss (APL) equations of BR are derived with the transmitter operating in electronic scanning and mechanical scanning modes. The APL plots of BR are simulated under the condition of different bistatic geometry positions. Simulated results show that the APL loss of BR is less than that of monostatic radar.
