塔康系统单站无源侦测定位研究

Research on Single Observer Passive Localization Method for TACAN System

利用塔康系统询问-应答规律,提出了一种对塔康机载设备无源单站侦测定位方法,通过测量询问、应答信号的到达时间及两信号来波夹角,采用位置线交叉法实现定位。通过理论分析和计算机仿真,证明了该方法的可行性。较之于双站定位方法,该方法系统简单,无需复杂的时间同步,对工程实践有一定的指导意义。

Based on the principle of interrogator, a passive localization method for the airborne responder of TACAN system with single sta- tion is put forward. Position-line-crossing is used in the method by measuring the time-difference-of-arrival and the included angle of inquir- y and response signal. The method has been proved practicable by theoretical analysis and MATLAB simulation. Compared with dual sta- tion location method, it has a simple system and needn ＇ t complex time synchronization. It is reasonable for engineering practice.
