首先，建立了任意机载双基地雷达配置情况下的杂波回波模型；然后，分析了双基地机载雷达主杂波多普勒频率展宽与发射和接收平台配置的定量关系，推导了在不同情况下使主杂波频谱展宽最小需要满足的数学条件，并给出了具体的数学表达式；最后，通过仿真验证了文中对主杂波频谱宽度与双基地配置关系分析的正确性。

In this paper, the clutter echoes model of bistatic airborne radar for arbitrary geometric configuration is established, and then the relationship between the Doppler frequency spread of the mainlobe clutter in bistatic airborne radar and the geometric configuration of bistatic airborne radar is analyzed, the mathematic qualification for minimizing the Doppler frequency spread of the mainlobe clutter is derived and the expression is given. The simulations validate the analysis of the relationship between the frequency width of mainlobe clutter and geometric configuration.
