摘要
为保护特定辐射源目标,对常规无源侦察系统信号分选过程使用的聚类机理开展反侦察技术研究。对探测侦察获取的全脉冲信号进行参数特征分析,挖掘可供利用的对抗薄弱点,提出一种针对聚类算法的有效干扰措施。通过辐射干扰信号,使得接收机在获取后产生冗余的脉冲描述字数据,进而影响分选告警结果,使其产生偏差甚至是错误的信息,从而有效破坏侦察意图,实现对高价值目标的辐射源的电磁防护。研究成果已在实际工程研制项目和预先研究项目中得到了应用,并获得了较明显的实际使用效果和肯定,仿真结果说明该方法的可行性与有效性。
In order to protect the specific emitter, the anti-reconnaissance technology researcn ~s carried out on the clustering mechanism used in the signal sorting process of conventional passive reconnaissance system. The characteristics of the full pulse signal acquired by the detection and reconnaissance are anaylzed, and also the vulnerability. An effective interference measure for the clustering algorithm is put forward. Under the influence of the jamming signal, redundant pulse description word data are generated by the receiver, thereby the sorting results are affect- ed, and deviated or even wrong inform are given. So it finally fails to detect high-value target effectively. The research results are applied in practical project and pre-research projects, and the practical effect and affirmation are obtained. The simulation results show the feasibility and effectiveness of this method.
