ARUAV前沿判别法抗多点源诱偏性能研究

基于反辐射无人机的时域鉴别技术，提出了一种以小波分析为手段的前沿判别法。将被动雷达导引头使用固定波门对脉冲前沿进行采样所得的信号作小波分析，对分析结果进行判定，当判定采样信号内为单辐射源信号时对其进行测向、测频、跟踪和打击。针对两点源诱偏系统分析表明，在大部分空域中，反辐射无人机总是能首先跟踪诱饵信号。通过建模与仿真，验证了前沿判别法能够有效对抗两点源诱偏系统，并由固定波门得到了有效的判别空域。

Performance analysis of pulse leading-edge distinguish technique of ARUAV on Countering Multi-Source Decoy Radar System

According to time discrimination technique of anti-radiation unmanned aerial vehicle(ARUAV), pulse leading-edge distinguish technique is put forward based on wavelet analysis. The passive radar seeker(PRS) uses fixed strobe gate to sample the pulse leading-edge, and analyze it using wavelet. When the analysis result verifies that the sample includes only single radiation source, the PRS will measure the sample signal direction and its frequency, track the sample signal, and attack the source target. When facing two radiation sources system, the analysis results show that the PRS can track decoy signal firstly in most position of the airspace. By modeling and simulation, it is verified that the pulse leading-edge distinguish technique can effectively counter two radiation sources system, and find effective discretion area from the fixed strobe gate.
