| 摘 要： | 为解决宽频带测角模糊,利用弹体旋转带动天线旋转式相位干涉仪,提出了基于开环旋转干涉仪测向方法,并分析了其解模糊原理.相比于闭环旋转干涉仪测向,有实现结构简单、覆盖更宽雷达重复频率范围等优点,仿真结果表明,提出的方法在解决测角模糊的同时,具有优良的测角精度.

| Abstract: | It is well known that the interferometer is very important in direction finding and position of targets. The arrangement of the open loop algorithm in the direction finding by the method of the rotating interferometer system and the performance of the system were studied in this paper. The interests focus on the approach of resolving the ambiguities for angle of arrival and of increasing measurement accuracy of direction finding. The simulation results show that the new algorithm is available for the estimation direction of arrival (DOA) and confirm the feasibility and correctness of the algorithm described. |
