摘要

Abstract: We propose a new approach to compensate for reflector deformation losses by using an array of identical receiving antenna feeds in the focal plane of the reflector. Our approach is an optimum combining algorithm that minimize SNR losses depend on unknown radio source and system noise correlation parameters that need to be estimated. A singular value decomposition method is used in conjunction with sampling estimates to obtain these unknown parameters and arrive at estimated weight coefficients. The actual combined signal SNR using these estimated weight coefficients are derived. An operational environment using the Jet Propulsion Laboratory 34 meter antenna at 33 GHz is considered using a seven feed array. !8
