反辐射武器采用幅度检测抗诱饵技术探讨

针对反辐射武器面临的有源诱偏威胁,分析诱饵系统与主雷达在空间布局上的特点,提出转动PRS（被动雷达导引头）接收天线,然后根据信号幅度变化信息将各辐射源区分开的新方法。以抗3点源诱偏为例,从幅度分辨能力、平台运动和雷达天线波束扫描对幅度检测的影响等方面分析说明方法的可行性,并通过试验验证了,PRS可通过提高幅度分辨能力来提高角度分辨抗诱偏能力,同时说明了其在时域分辨、门限检测、天线伺服控制等方面需满足的条件。

Analysis of Amplitude Discrimination for Anti-Radiation Weapons Against Active Decoys

Following analysis of the features of spatial layout between decoys and radars in an active decoy environment for anti-radiation weapons,this paper proposes a new way to distinguish signals of multiple sources by turning PRS(passive radar seeker) antenna and observing variation of amplitude of the signals.The feasibility of the method is analyzed from the perspectives of amplitude discrimination,platform movement and antenna scan.Test results show the angle resolving performance of PRS can be replaced by amplitude discrimination performance.Required conditions including time domain discrimination,threshold detection and servo control of the antenna are described.
