Mitigation of multipath propagation with the use of a non-uniform spaced adaptive array antenna

The paper presents a method to mitigate the effect of multipath propagation using an adaptive array antenna. It is shown that, by controlling the number of active elements and their spacing, the array´s capability to eliminate scattered signals can be enhanced in the presence of pointing errors. We consider a non-uniform inter-element spacing of the array. In practice, this can be achieved by switching some elements on or off electronically, and/or by mechanical displacement of the elements.
