摘要

PURPOSE: To reduce weight, miniaturize housing and increase reliability of a window shade radar antenna. CONSTITUTION: A lens assembly for a window shade radar includes two adjacent membranes 16A, 16B rolled onto separate rollers. One ends of expandable side masts 20A, 20B are fitted to foldable beams 33A, 33B, and the other ends are pivotally secured to rollers 34A, 34B by slip joints 36. Main beams enclose wire busses 48 which are directly connected to membrane modular antenna elements without interposed rotary connections.
