Fu Demin · Dianzi xuebao · 2002
Based on a single snapshot data,the effect of mutual coupling on the performance of adaptive arrays is studied.Firstly,the signal processing method based on a single snapshot data is demonstrated,the method of constructing the equations for solving the weight is introduced,and the expression for the reconstructed desire signal and the formula for the adaptive pattern are given.Then,applying the MOM analytic model and the forward method,the effect of mutual coupling between elements is analyzed.The method of mutual coupling compensation in adaptive arrays is proposed.Finally,the effect of mutual coupling on the resolution and the output pattern of adaptive system and the compensation results of the given methods in this paper are simulated with existence of strong or weak interference.
