摘　　要：根据塔康信号询问脉冲与应答脉冲之间的规律,提出一种针对空中机载塔康终端的单站定位方法。首先采用测向交叉定位法得到地面信标台的位置,然后利用询问应答规律,获得询问信号分别到达侦察站与信标台的时间差,再加上对空中目标的测向信息,即可实现对空中目标的定位。通过MATLAB程序仿真证明了该方法的可行性,对于解决实际工程中的定位问题具有借鉴意义。According to the regulation between TACAN interrogation signal and response signal,this paper proposes a single-station location method for airborne TACAN terminal.In this method,the position of ground beacon station is obtained by using direction finding cross location,and the interrogation-response regulation is used to measure the time-difference-of-arrival(TDOA)of TACAN interrogate and response signal at reconnaissance station.Combining with the direction finding information for air target,the location for air target is implemented.The MATLAB simulation results show that the proposed method is feasible,and it can provide reference for implementing location in practical engineering.
