The Analysis of Using Spatial Smoothing for DOA Estimation of Coherent Signals in Sparse Arrays
When there is coexistence of uncorrelated and coherent signals in sparse arrays, the conventional algorithms for direction-of-arrival (DOA) estimation using difference coarray fail. In order to solve the problems, this paper analyzes the feasibility of using spatial smoothing in sparse arrays. First...
