摘要
有效干扰扇面是评估分布式干扰效能的一个重要指标。在分布式干扰执行掩护突防任务的背景下,首先建立了单干扰机对雷达的有效干扰扇面模型;然后应用图示法推导了基于雷达天线方向图的分布式干扰有效干扰扇面的解析表达式,分析讨论了不同角度条件下有效干扰扇面的大小,提出了最佳干扰角度的概念;最后开展了仿真研究,仿真结果验证了理论分析的正确性。可为制定正确的干扰策略提供有益的指导和参考。
Effective jamming sector is an important index for the efficiency evaluation of distributed jamming. Under the background that distributed jamming carries out covering penetration task. Firstly the effective jamming sector model is set up for single jammer. Then the analytical expression of distributed jamming effective jamming sector is deduced based on radar antenna pattern with diagram method, the values of effective jamming sector are discussed with different angles between two jammers, and the optimal angle is put forward. Lastly the simulation work is done, and the correctness of the theoretic analysis is validated with the simulation results. The theoretic analysis and simulation results are instructive for making a reasonable jamming tactic.
