Angle Estimation for MIMO Radar Based on Fourth-Order Cumulants
摘要
Abstract
A new algorithm based on fourth order cumulants is proposed for angle estimation for MIMO radar in the presence of the spatially Gaussian noise,which constructs a cumulant matrix using the data vectors of radar.Through the eigenvalue decomposition of the matrix,angles of MIMO radar can be estimated combining with the subspace kind algorithms such as MUSIC and ESPRIT.This algorithm,keeping the capacity of virtual array extending and target distinguish,removing data redundancy of cumulant matrix and reducing the complexity,restrains automatically the influence of the Gaussian noise and will be more available in practice.Simulation results verify that the proposed algorithm is effective.关键词
