复杂电磁环境对雷达作用的正常发挥提出了更高的要求,其直接影响雷达对目标的探测能力。文中分析了压制性干扰对警戒雷达发现概率和探测距离两个主要性能指标的影响，并对复杂电磁环境下警戒雷达探测性能进行了验证。同时，提出了利用探测性能评估机载警戒雷达抗压制干扰能力的方法。

The complex electromagnetic environment propose a higher request to the normal display of radar function,it influences the airborne radar detection performaences directly. The influence of oppressive jam to the warning radar's detection probability and detection range is analyced. And detection performance is tested through flight test in complicated electromagnetic environment. In addition, the way of evaluation about airborne warning radar anti oppressive jamming ability is given by detection performance.
