摘要
基于频率分集雷达原理,并与单频雷达进行比较,分析了频率分集雷达的抗干扰效能,同时对其进行建模。该模型包括抗干扰改善因子的计算模型、雷达作用距离和发现概率的计算模型。通过建模分析得出:在总功率与单频雷达保持相同的情况下,频率分集雷达并不能改善雷达接收到的信干比,频率分集雷达实现抗干扰的途径是提高雷达工作的可靠性,而不是提高雷达对目标的检测性能。
Based on the frequency diversity basic theory, compared with single frequency radar, the counter-jamming effectiveness for frequency diversity radar is analysed and modeled. The model includs counter-jamming improvement factors, radar detection range and detection probability. The models analysis concluds that the frequency diversity radar couldn't improve the received signal-to-jam ratio with the same total power. The reason of frequency diversity radar can weaken jamming effectiveness is that it can improve the reliability of radar, not the detection capability.
