主　　题：direction-of-arrival(DOA)estimation two parallel linear arrays PM algorithm 

摘      要：In this paper,a two-dimensional(2 D)direction-of-arrival(DOA)estimation algorithm with increased degrees of freedom for two parallel linear arrays is *** different from the conventional two-parallel linear array,the proposed two-parallel linear array consists of two uniform linear arrays with non-equal inter-element *** method(PM)is used to obtain a special matrix which can be utilized to increase the virtual elements of one of uniform linear ***,the PM algorithm is used again to obtain automatically paired elevation and azimuth *** simulation results and complexity analysis show that the proposed method can increase the number of distinguishable signals and improve the estimation precision without increasing the computational complexity.
