摘要
寻求一种快速解相位模糊算法,是实现多基线干涉仪高精度快速测向的关键问题。为此,从理论证明、特例分析、仿真验证等角度,分析了基于1维主搜索、(M-1)维从搜索快速解相位模糊算法在应用中存在的问题,并提出了一种新的改进算法,计算机仿真表明了这种算法的可行性。这种算法还可以应用在采用参次频差比相测距中的相位解模糊问题,有一定的工程应用价值。
Finding a fast algorithm for unwrapping Phase Ambiguity is very important in direction finding while using multi-baseline phase interferometer. So, the problem of a fast algorithm used for unwrapping phase ambiguity is analyzed in different aspects. Then an improved fast algorithm is given. The algorithm's feasibility is verified by our computing simulation results. It would be interesting to apply this algorithm to unwrapping phase ambiguity in the measurement of range by phases under stagger relation of frequency difference.
