Method of resolving ambiguity for sparse array via modified sparse even array based on MUSIC Algorithm

摘要：

A novel method of resolving ambiguity via modified sparse even array based on MUSIC algorithm is proposed in this paper.Firstly,uses the data from original array to do DOA;Then,modified the array slightly.Finally,uses the two received data to do DOA in the same reference frame.which can separate the ambiguity angle from the two spectrum functions to get the real DOA. At the same time,the least adjust value of resolving ambiguity is given.In additional,both the measure function of resolving ambiguity and the relationship between resolving ambiguity ability and glip space are given.Simulation results and performance analysis verify that the algorithm is effective and feasible.
