Low radar reflection glazing element for building near airport radar installation - has thick front glass pane sepd. by wide space from back glass contg. electroconducting layer

摘要

Low radar reflection glazing element has a 4-15 mm thick front glass pane (1) sepd. by a 6-24 mm wide gas space from a back glass pane (2) which has, on its surface facing the front glass pane, a translucent electroconductive layer (3) with a surface resistivity of 1200-3500 ohms/sq.cm./mm front pane thickness. USE/ADVANTAGE - For fitting in building walls located within the range of stationary airport radar equipment and which are oriented perpendicular to the radiation direction. Element has a smooth outer surface (for improved appearance and easy cleaning) and has low radar reflection (less than 10%, pref. less than 1% vertical incidence) esp. in the 1 GHZ region to reduce radar noise.
