基于参差距离的相位差变化值的解模糊方法研究

利用相位差及其变化率对辐射源进行定位是新近提出的一种快速单基无源定位方法。本文分析了利用相位干涉议得到的相位差变化值的相位模糊特点,提出了一种利用相位干涉仪的接收天线之间的参差距离对相位差变化值进行解模糊的方法,讨论了正确解模糊的条件和范围,并给出了仿真结果。

Analysis of the Method in Solving Phase Difference Variety Ambiguity with Stagger Distance Difference

By employing phase difference and the rate of phase difference measured by phase interferometer, a new passive location system can locate the position of emitter more quickly with higher precision. In this paper, we propose a new method to solving the phase difference variety ambiguity by using stagger distance difference after analysis of the phase difference. We also give the condition of correctly solving the ambiguity equation account for this. The condition is proved by simulation.
