摘　　要：针对空基双基地雷达杂波仿真中，地面杂波分辨单元面积的计算问题，通过建立空基双基地雷达几何关系，分析了其距离特性，提出了一种宽波束发射、窄波束接收，空间同步方式的空基双基地雷达系统杂波仿真中双基地雷达杂波分辨单元的计算方法。该方法利用双基地雷达距离特性和面积分的方法，推导出了由接收机带宽和波束宽度决定的杂波分辨单元面积的精确解析式。Aiming at the ground clutter resolution cell area computational problem of airborne bi- static radar clutter simulation, a computation method is presented by establishing airborne bistatic radar geometrical relationship and analyzing the range characteristics with broad transmit beam and narrow receive beam of bistatic radar.
