摘　　要：研究了任意机载双基雷达构型的几何配置关系,采用以地面杂波散射点坐标为变量的杂波建模方法,给出了空时杂波回波的仿真公式。在考虑收发双站共视区域、大气传播损耗、天线阵元因子、阵元通道幅相误差、地面反射系数等条件下,对机载双基雷达杂波阵元级回波进行仿真,为进行机载双基杂波抑制算法研究提供阵元级数据支持。This paper studies the geometry configuration relationship of any airborne bistatic radar,by using the clutter modeling method taking the ground clutter scattering point coordinate as the variable,gives the simulation formula of space-time clutter echo.Under the conditions considering the common viewing area of receiving and transmitting stations,the atmospheric propagation loss,antenna element factor,amplitude and phase error of element,ground reflection coefficient,etc.,simulates the element level clutter echo of airborne bistatic radar,which provides the element level clutter data support for the study of airborne bistatic clutter suppression algorithm.
