【Abstract】 An effective hybrid method for compensation the effect of mutual coupling on the performance of adaptive arrays is proposed. By using the wavelet transformation and the method of moments, the signal input to the adaptive processor with mutual coupling taken into account is computed fast. In accordance with the maximum ratio of signal to interference and noise, the expression for the weight that compensates the mutual coupling is given through the spectral method. Finally, the adaptive beam of a linear array with mutual coupling compensated is simulated, which shows the validity of this method.\;更多还原
