摘要: An effective sparse array extension method for maximizing the number of consecutive lags in fourth-order difference co-array is proposed, leading to a novel enhanced structure based on co-prime arrays (CPAs) with significantly increased degrees freedom (DOFs). One exploit DOFs nonstationary signals also with simulation results provided demonstrate effectiveness proposed structure.
