VERFAHREN UND SCHALTUNGSANORDNUNG ZUR DARSTELLUNG VON RADAR-ECHO-SIGNALEN

摘要

A process for displaying radar echo signals allows brightness modulation signal of the radar picture to be derived from the radar echo signal. In order to avoid brightness overmodulation in the case of flat, wide echo structures, and to improve detail recognition, the flat echo structures of extensive reflecting objects that appear on the radar picture are reproduced around their outer outlines (contour) with high intensity, whereas the inside of their surface is reproduced with a strongly reduced intensity. A highly contrasted image with a cartographic appearance is thus obtained, in which even smaller targets or targets with bad reflecting properties, thus lower intensity, can be very well recognized.
