Improved Optimization Method for Array Feed Calculations
نویسنده
چکیده
Reflector antenna optimization schemes using array feeds have been used to recover antenna losses resulting from antenna distortions and aberrations and to generate contour coverage patterns. IIistorically these optimization have been carried out using the antenna far-field scattered patterns. The far-field patterns must be calculated separately for each of the array feed elements. For large or complex antennas the far-field calculation times can be prohibitive. This paper presents a method that allows the optimization to be carried out in the antenna focal region where the scattering calculation needs only to be done once independent of the number of the elements in the array.
