摘要: 針對(duì)多基線相位干涉儀在寬帶測(cè)向時(shí)存在的問題,該文提出了一種基于中國(guó)余數(shù)定理的相位差解模糊算法,研究了噪擾條件下正確解模糊的條件。該方法選擇基線長(zhǎng)度滿足一定的參差關(guān)系,從而解決了測(cè)向精度與最大不模糊角度之間的矛盾。計(jì)算機(jī)仿真證明了該方法的有效性。

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. -
