非固定比例干涉仪测向算法

Direction Finding Algorithm of Interferometer without A Fixed Proportion

干涉仪测向技术具有原理简单、测向精度高、实时性好等优点,但是该技术在测向时存在相位模糊的问题。针对这个问题提出了几种利用多基线干涉仪对相位差进行解模糊的办法,并给出这几种算法的比较,对实际工程应用有一定参考意义。

Interferometer direction finding technology is provided with the advantages such as simple principle,good direction finding accuracy and real time,etc.,but the phase ambiguity is existed during direction finding.Aiming at the problem,this paper puts forward several methods using multi-baseline interferometer to solve ambiguity for phase difference,and gives the comparison of these algorithms,which has definite reference meaning for actual engineering application.
