Abstract :
A new decoupling algorithm is proposed to estimate DOA of rectangle array with mutual coupling. The new algorithm can jointly estimate signal source direction and coupling parameters of array. This algorithm transforms joint problem into cascade problem and gets the parameters by one dimension spectrum peak value searching, which avoids multidimensional nonlinear searching of multi-parameters joint estimation. The simulation results validate the good performance of the proposed algorithm.
