Analysis of the research status of phase interferometer deblurring

Abstract

Interferometer direction finding technology has the advantages of simple principle, high accuracy, and good real-time performance. It is commonly used as passive direction-finding technology in electronic detection system. However, the problem of phase ambiguity exists in direction finding. In order to solve the fuzzy problem of direction finding in the interferometer, three methods of solving the fuzzy problem are introduced: one-dimensional baseline method, multi-dimensional baseline method and rotating baseline method. The characteristics and applicable conditions of various methods are analyzed, which are of certain reference significance for practical engineering application.
