压制性噪声干扰是机载相控阵雷达中最重要的干扰形式。首先,分析了机载相控阵雷达压制性噪声干扰的特点;然后,按照同时抑制和级联抑制两种形式对现有抗压制性噪声干扰方法的基本原理和优缺点进行了分析;最后,通过仿真实验比较了各种抗压制性噪声干扰方法的干扰抑制性能,并给出了两种典型抗压制性噪声干扰方法的运算量。

Barrage noise jamming is the most important jamming method for airborne phased array radar. Firstly, the characteristic of barrage noise jamming is analyzed in this paper. Then, the theory, advantage and disadvantage of existing jamming suppression methods are analyzed according to simultaneous or cascaded jammer and clutter suppression mode is also analyzed. Finally, the performance of jamming suppression methods is compared through simulation, and the computational load of jamming and clutter suppression methods is presented.
