| Abstract: | By constructing fitness function for 2 D WSF algorithm and optimizing with genetic algorithm based on multiple rings of uniform circular arrays(UCA), the 2 D DOA estimation of multiple noncoherent or coherent sources with high precision, high resolution and good robustness in wide band is obtained. Computer simulations indicates the validity of this algorithm. |
