自提取模板序列机载雷达威胁告警算法

A Threat Warning Method of Airborne Radar with Self-Extraction Template Sequence

针对机载雷达如何实现快速威胁告警这一问题,基于模板序列的描述方式,提出一种自提取模板序列威胁告警算法实现对截获敌方雷达信号的快速提取,算法利用同种雷达信号脉冲之间的匹配相关性,通过脉冲的整体平移,在实现对模板序列自提取的同时,把用此模板序列描述的雷达辐射源信号提取出来,从而对该雷达进行威胁告警。仿真实验表明,在有脉冲漏失的信号环境中,文中算法处理脉冲信号与传统多参数统计方法性能相当,可以获得较高的成功率。

Aiming at the problem of how to implement rapid threat warning for the airborne radar,a threat warning method with self-extraction template sequence is put forward,based on the descriptive ap-proach of template sequence to realize the rapid recognition of intercepted enemy radar signals in this paper. This method employs the matching correlation between pulses received from the same radars,and through shifting the full pulses,the self-extraction of template sequence can be realized.In the meantime,the radar emitter signals described by such template sequence can also be filtered.Simulation results show that,in the signal environment with pulses missing,the proposed method can reach the same effect in processing pulse signal as the traditional multi-parameter statistical approach,and the high success rate can be obtained.
