Abstract	Introduction: During t h e period from November 1998 through February 1999, a series of measurements was carried out on the 70-m antenna at DSS 14 to determine t h e performance characteristics of two systems designed to compensate for the effects of elevation-dependent gravity distortion of the main reflector on antenna gain. The array feed compensation system (AFCS) and the deformable flat plate (DFP) system were both mounted on t h e same feed cone and each was used independently as well as jointly to measure and improve the antenna aperture efficiency as a function of elevation angle. The experimental data is presented in [I] and [2]. This write-up contains a description of the computational method and theoretical results for the DFP and Array Feed systems. The basic analysis tool is a Physical Optics reflector analysis code that was ported to a parallel computer for faster execution times. There are several steps involved in computing the RF performance of the various systems.
