TACAN信号侦收处理技术

Reconnaissance Receiving and Processing Technique for TACAN Signals

介绍了TACAN信号的格式和基本特征,提出了一种通过对TACAN信号的分选、识别,获得主、辅基准群脉冲,计算基准群与包络相位零点之间的相位差,得到TACAN方位信息的处理方法。利用MATLAB对TACAN信号分选以及方位处理进行了仿真分析。仿真结果表明,此方法能够获得精确的TACAN方位信息。

The format and characters of TACAN signal are introduced, a method is proposed that the major reference group and auxiliary reference group are sorted from TACAN signals, then phase difference between reference group and zero phase of envelope is calculated to get the information on its position relative to ground station. Signal sorting and the bearing processing are analysed based on MATLAB. Simulation results show that the algorithm can get the precise bearing information of TACAN.
