RADAR ANTI-FADE SYSTEMS AND METHODS

A method for suppressing ground return radar fading in a radar altimeter (10 ) is described. The method includes providing a radar gate width which corresponds to an area (140) that is smaller than an antenna illumination ar ea being impinged by transmissions of the radar altimeter, dithering the ra...

Zusammenfassung:	A method for suppressing ground return radar fading in a radar altimeter (10 ) is described. The method includes providing a radar gate width which corresponds to an area (140) that is smaller than an antenna illumination ar ea being impinged by transmissions of the radar altimeter, dithering the radar gate viewing area (102) within the antenna illumination area being impinged by transmissions of the radar altimeter, and taking radar return samples with t he radar altimeter.
