Forward Looking Airborne Radar for Landing Aid

A forward-looking 36 GHz radar for aircrafts and helicopters is presented. It uses the rotating synthetic aperture for obtaining the azimuth resolution and independent radars with different antenna elevation angles for obtaining the elevation resolution. Main radar functionalities are the guidance for landing phase including the three-dimensional view, strike avoidance, moving target indication and detection of stationary air and ground obstacles. This article describes the radar principle, its modeling and an implementation example for a given operational requirement.
