| 摘 要： | 针对机载双基地雷达在强杂波环境下作用距离不满足雷达方程的问题,基于等熵原理建立了雷达信噪比和信杂比的转换关系,给出了机载双基地雷达杂波分辨单元面积的计算方法,根据信杂比的定义推导了杂波环境下的雷达方程,理论和仿真分析表明,杂波干扰明显降低了的雷达作用距离,杂波类型、波束俯角、宽度和脉冲宽度等因素对杂波环境中雷达的探测距离影响显著.

| Abstract: | Aiming at the problem of bistaic radar detection range under clutter circumstance which doesn't satisfy the radar range equation, a transform relationship between radar SNR and SCR is formed, the calculate formulae of area of bistatic radar clutter cell are presented, and the radar range equation under clutter circumstance is studied. The formulae and emulations both indicate that clutter can reduce the detection range of bistatic radar badly, the parameters such as kind of clutter, elevation angle of receive beam, width of receive beam and pulse signal have great impact on bistatic radar range when under clutter circumstance. |
