Adaptive Spatial and Temporal Selective Attenuator in the Presence of Mutual Coupling and Channel Errors

Ilir F. Progri and William R. Michalson

Abstract:	An adaptive spatial and temporal selective attenuator (ASTSA) can be used to mitigate the effects of undesired narrow and/or wideband signals. This can be accomplished by applying a set of multipliers, which seeks to maximize the sensitivity in the direction of the desired signal(s) and minimize the sensitivity in the direction of the undesired signal(s). This minimization and/or maximization criterion is defined as the undesired over desired ratio (UDR). The presence of mutual coupling and channel errors will distort both the desired and the undesired signal(s) thus producing a different set of multipliers utilizing the UDR ratio. The effect of mutual coupling and channel errors on the UDR ratio is analyzed and presented in this paper.
