对机载轰瞄雷达的多站协同干扰压制区计算
|
摘要
基于多干扰站空间功率合成理论及协同干扰理念,讨论了在各干扰站发射信号到达机载轰瞄雷达处的相位可精确设置与相位呈随机均匀分布两种情形下的干扰功率合成计算,构建了要地防空作战背景下对机载轰瞄雷达的多站协同干扰压制区计算模型,并进行了示例仿真分析。分析结果表明,与传统的计算干扰压制区的直接叠加法相比,基于空间功率合成理论的整体求值法能够获得更大的有效压制区。论文研究内容可为地对空雷达干扰效能分析评估以及地对空雷达干扰力量优化决策提供科学合理的参考依据。
Firstly,based on the spatial power-combining theory of multiple different radar jamming signals and the coordinated jamming concept,the two power-combing calculation methods of jamming signals when jamming signals' phases are randomly uniform distributed or precisely set are discussed in this paper. Secondly,the jamming blanketed zone computing model of multiple radar jammers is established in point Defensive Counter Air( DCA) combat circumstance which radar jammers are used to jam airborne targeting radar. Thirdly,some simulation examples are analyzed at the end of the paper. The simulation results show that jamming blanketed zone using overall evaluation method based on spatial power-combing theory is larger than direct superposition method.The research work in the paper not only provides scientific and reasonable references for ground-to-air radar jamming effectiveness evaluation,but also provides the basis calculating models for the optimum usage of ground-toair radar jammers.
