摘要: 针对多基线相位干涉仪在宽带测向时存在的问题,该文提出了一种基于中国余数定理的相位差解模糊算法,研究了噪扰条件下正确解模糊的条件。该方法选择基线长度满足一定的参差关系,从而解决了测向精度与最大不模糊角度之间的矛盾。计算机仿真证明了该方法的有效性。Abstract: For the problem of multi-baseline interferometer in wideband direction finding, a algorithm of solving multi-baseline interferometer phase difference ambiguity based on Chinese remainder theorem is given and the condition of correctly solving ambiguity in noisy circumstance is studied. The algorithm selects baseline length satisfied stagger qualification, thereby solving conflict between accuracy of direction finding and maximum unambiguity angle. The performance of the algorithm is effectively demonstrated by computer simulation.
