Abstract

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.
