US 2012/0268312 A1 · METHOD FOR MONITORING THE LAW OF ILLUMINATION OF A RADAR ANTENNA AND CORRESPONDING DEVICE

Abstract

A method for controlling laws of illumination of a radar antenna with adjustable gain and/or phase, suitable for sending and for receiving a radar signal, the method including obtaining a position of an obstacle located in a near field of a beam of the radar antenna according to a direction of aim of said beam, calculating the laws of illumination on sending and on receiving of said radar antenna so as to adjust the direction of the aim of the radar beam while minimizing interaction and/or effects between the beam of the radar antenna and the obstacle, and implementing the calculated laws of illumination on sending and on receiving of the radar antenna.
