Antenna Technology for Space-Based Radar. Part 2. Estimation of Blockage Side-Lobe Levels for the Space-Based Radar Antenna

摘要

Side-lobe levels due to blockage effect of the boom connecting the feed to the lens of the space-based radar antenna are estimated. Also, the effect of antenna stays on side-lobe levels is calculated. It is shown that side-lobe levels exceeding -50 dB are produced by the boom. (Author)
