The Tamed Adaptive Array for Imperfect Constraint Due to Mutual Coupling or Random Input Errors
Summary :
The adaptive array under the principle of directionally constrained minimization of power (DCMP) operates to minimize the output power under the constraint to maintain the specified response to the direction of the desired signal. This constraint depends on the a priori knowledge of the relation of the output at each element of the array with respect to the desired signal. If this setting contains some error, the desired signal will be taken for the unwanted one and hence become a target of suppression. To prevent this malfunction, we introduce a modified system of DCMP, which is named the tamed adaptive array, and demonstrate its effectiveness against such imperfect constraint. We consider two examples that cause such effects, i.e., the mutual coupling and random input errors, and numerical results show that the tamed system is robust against those influences.
