Abstract
A new decoupling algorithm is proposed to estimate DOA of concentric uniform circular arrays (C-UCA). The new algorithm can calibrates mutual coupling of the inner sub-arrays, compensate for mutual coupling between sub-arrays, and then estimate DOA of signal sources. 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 and theoretic analysis validate the good performance of the proposed algorithm.
