一种利用询问－应答规律对应答机定位的方法

针对双站测向定位系统复杂、同步要求高的问题，根据询问应答机的工作规律，提出了一种对应答机单站定位的方法。根据已知的地面询问站和侦收站位置，通过测量敌我识别询问和应答信号到达时间差和应答信号方位，实现了对应答机的定位；同时分析了定位误差，通过计算机仿真证明了该方法的可行性。在地面询问站已知的情况下该方法对于解决实际工程问题具有借鉴意义。

A locating method based on regulation of interrogate-response signal

Based on the principle of interrogator,a new method for locating the responder with single station is proposed,which avoids the problem that the double-station locating system is complex and the requirement of synchronization is high.According to the known positions of the interrogator and the reconnaissance station on ground,by measuring the time-difference-of-arrival(TDOA) of the identification friend or foe(IFF) inquiry and response signal and the azimuth of response signal,the method can locate the responder,and the location accuracy is analyzed.The method has been proved practicable by computer simulation.The method has reference significance for solving practical engineering problems when the position of the inquiry station is known.
