Airborne radar with wide angular coverage, in particular for the function for detecting and avoiding obstacles

摘要

The device has a transmitting system (21) including a transmitting antenna provided with linear arrays (111-113) of radiating elements (2) focusing a transmitting beam. Power amplifiers amplify transmission signals produced by waveform generators (25, 26), respectively. A control unit is provided with switches (27, 28) to control the corresponding signals produced by the generators, and supplies the signals to the elements. The elements are controlled for simultaneously producing electronic scanning of the transmitting beam in elevation and colored transmission in elevation. The waveform generators provide respective coloring waveform and pulsed sinusoidal waveform.
