摘　　要：接收机在欺骗干扰环境下直接进行信号捕获时,会出现捕获错误或捕获失败,将得到错误的处理信息甚至作出错误决策.针对接收信号易受敌方欺骗干扰的问题,接收机在信号捕获阶段采用信息辅助、多峰检测、精确测频等方法,具备较优的抗欺骗干扰能力,并加快信号捕获的处理速度.试验与分析表明:无论转发式、产生式干扰源,或者静态、动态干扰源,接收机在信号捕获阶段采用抗欺骗干扰技术后几乎可辨识并消除所有种类的欺骗干扰.The receiver occurs acquisition errors or failures when directs signal acquisition in the deception jamming environment,even obtains false processing information or makes false decisions. Aiming at the received signal susceptibly encountered the enemy deception jamming, some algorithms as information-aided, multiple-peak detection, accurate frequency measurement in the process of signal acquisition are utilized, getting superior ability of anti-deception jamming and accelerating the process speed of signal acquisition.The experiments and analysis verify that the receiver almost identifies and eliminates all kinds of deception jamming, no matter the repeater/generator jammer or the static/dynamic jammer, when the signal acquisition uses anti-deception jamming technologies.
