一种基于干涉仪布阵的方位俯仰相关测向方法

A Direction Finding Method of Azimuth and Elevation Correlation Based on Interferometer Array

干涉仪测向具有测向精度高、工程可实现程度高等优点,广泛应用于电子侦察领域。但由于天线罩、机体环境等安装位置附近物体影响,会对接收天线引入相位误差,可能导致干涉仪测向解模糊错误。针对干涉仪测向存在的解模糊问题,提出了方位俯仰联合相关的解模糊方法,并通过仿真计算,验证了该方法的正确性。

Interferometer direction-finding is widely used in electronic reconnaissance because of its high precision and high degree of engineering realization. However, due to the influence of objects near the installation positions such as radome and airframe environment, phase errors will be introduced into the receiving antennas, which will lead to the mistake of direction-finding. Aiming at the problem of ambiguity resolution in the interferometer direction-finding, a direction-finding method of azimuth and elevation correlation based on interferometer array is put forward. By means of simulation, the correctness of the method is verified.
