摘　　要：对高价值目标敌我识别系统的侦察任务已日益迫切,主要针对敌我识别信号主被动一体侦察定位应用,在分析其工作原理和工作流程的基础上,提出了对敌我识别应答信号的主动探测手段,并给出主/被动模式下的单站定位算法,相关技术可有效提高系统发现并跟踪目标的概率。The requirement for reconnaissance of the IFF signal of high-value targets has become increasing⁃ly urgent.The application of active and passive integrated reconnaissance and positioning of the IFF signal are mainly studied.Based on the analysis of the working principle and workflows in the IFF system,an active recon⁃naissance method to the IFF responding signal and the single-station positioning algorithm of the IFF signal in ac⁃tive and passive mode is proposed.The method proposed can effectively increase the probability of discovering and tracking the targets of the IFF signal.
