Modeling and Efficiency Analysis of Support Jamming Aiming at Cosecant Square Beam Radar

建立了支援干扰模型,给出了现代雷达压制系数计算方法,并针对余割平方波束,分别在方位平面和俯仰平面构建了方向图模型。然后,分析了支援干扰对余割平方波束雷达的干扰效能,提取了干扰扇面作为干扰效能评估的核心指标,并建立了计算模型,定量研究了干扰扇面与掩护距离、干扰距离、飞行高度等效能指标间的内在关系。最后,得出了影响支援干扰作战效能的定性结论。

A model of support jamming operations is modeled, and the computing method of suppression coefficient is given with modern radar. The cosecant square beam patterns are simulated respectively, in azimuth plane and in elevation plane. And then the operational efficiency of support jamming is analysed aiming at cosecant square beam radar. The blanket jamming sector is ex- tracted as the hard-core index of the jamming effectiveness, and the calculation formula is inferred. The intrinsic relationship be- tween blanket jamming sector and other efficiency indexes is quantificationally researched such as secure distances, jamming dis- tance, flying height and so on. Finally, the qualitative conclusions of operational efficiency in support jamming are educed.
