摘要
JTIDs信号的高跳速、宽频段、窄脉冲对测向提出了挑战，同时，现代战争的超视距打击能力使得其通信终端距离侦察设备越来越远，如何及时截获并测量其方位，不但要解决高灵敏度接收的问题，还要解决高精度测向问题。提出了一种基于JTIDS信号特点的测向方法，能够实现远距离侦收和高精度测向，同时系统是最简单的。
The high hop rate, wide bandwidth and short pulse of JTIDS signals present a challenge to direction finding. Simultaneously, the BLOS attack capability makes the distance between the communication terminals and our reconnaissance equipments longer and longer. Interception and direction finding of JTIDS signals in time require not only high receiving sensitivity but also high accuracy. In this paper, a new direction finding method for JTIDS signals based on its characteristics is given, which can realize long-range interception and high accuracy DF with a simple system.
