Abstract
This paper presents surface distortion detection and identification using bipolar measurements and microwave holography on a compact sub-reflectarray Cassegrain system. A ring-type distortion is added to the Cassegrain system which affects the performance of the overall system. Using microwave holographic diagnostics and measurements, the ring distortion is identified and its effect on the overall system is analyzed.
