Abstract:

In order to achieve good resolution with few elements, highly thinned arrays used in conjunction with adaptive antenna pattern control are commonly employed. This paper develops thinned array configurations optimized in performance in accordance with specific criteria. These criteria are used to optimize the element positions within the array considering both the close-in nulling resolution, and the average coverage area over a fixed, circular field of view for which it is desired that system users have positive link margin to a satellite at geosynchronous altitude. It is determined that the circular array configuration, with elements equi-spaced on the circle, generally produces the best close-in nulling resolution against arbitrary interference scenarios for large values of Dlambda.
