旋转干涉仪解模糊方法研究及实现

针对相位干涉仪估计波达角过程中的相位模糊问题,提出了一种新的基于旋转相位干涉仪解模糊的方法,对该方法的解模糊性能进行了仿真分析并和其它方法进行了比较,最后给出了测向系统的硬件实现方案.该方法解决了单基线干涉仪存在的视角范围和测角精度之间的矛盾,可在保证测向精度的条件下实现宽频带测向,并且只需两个接收通道,体积小.仿真结果及实际测向系统验证了该方法的有效性.

Study on Solving Ambiguity Method of Rolling Interferometer and Implemention

Focused on the problem of phase ambiguity when using phase interferometer to estimate the direction of arrival,a new ambiguity resolution method based on rolling phase interferometer was proposed.The performance of this method was analyzed and compared with other methods by simulation.Finally,the hardware scheme of direction finding system was given,which solved the contradiction between the angle range and the direction finding accuracy in the interferometer of single base line,and can realize the directio...
