一种基于目标的雷达对抗侦察策略

An Optimal Radar Reconnaissance Search Strategy Based on Prior-knowledge of Emitters

传统的电子战接收系统的搜索方式主要针对参数完全未知的敌方信号,通过在频域、空域等各维度进行大范围的逐段重复搜索可在较长时间内获得较好的侦察效果,但不适合短时间内对特定目标群的搜索和验证。针对电子战接收机存在的盲目侦察接收、与作战目标结合不紧密等问题,提出了一种基于作战目标的侦察策略,能够智能引导超外差接收机进行搜索截获,有效提升了超外差接收机对重点目标的实时截获与准确识别能力。

The traditional search strategy in electronic warfare is mainly aimed at signals whose parameters are totally unknown. The existing method can obtain good effect in the long run via repeated search pattern over the frequency domain,space domain and other dimensions. However,this approach is not suitable for specific target groups of search and verification within required time. This paper proposes a scenario examined in which a programmable,frequency-agile receiver is required to monitor a wide bandwidth for threat emitters from a known list. The novel search strategy basedon prior knowledge demonstrates obvious improvement on real-time intercepting and accurate recognition ability for superheterodyne receivers.
