Abstract

The invention relates to a glazing element which is transparent in the visible region of the spectrum and has a low reflectance for radar radiation of a frequency of approximately 1 GHz and a high reflectance for IR radiation. The glazing element consists at least of a first glass pane facing the radiation source and having a thickness of between 4 mm and 15 mm, and a second glass pane averted from the radiation source. The second glass pane carries an optically transparent, electrically highly conductive thin layer having a surface resistance of at most 50 OMEGA , and the first glass pane carries an optically transparent, electrically poorly conductive layer having a surface resistance of between 100 OMEGA and 600 OMEGA . The two electrically differently conductive layers are arranged at a radar-optical distance of at least approximately 30 mm - nglass (radar) . D and at most approximately 100 mm - nglass (radar) . D (D = total thickness of all glass panes between the radiation source and the poorly conductive layer on the first glass pane). <IMAGE>
