Abstract (en)

[origin: WO9905541A1] The invention pertains to an on-board radar equipment as part of the avionic system in an aircraft, said equipment providing a two-dimensional representation of the radar data from an area located upstream relative to the flight direction. The inventive radar equipment is an upstream sighting radar which gives of the radar data a high resolution and map-consistent representation from above in accordance with its basic operating mode resting upon the SAR(synthetic aperture radar)-based processing principle or an equivalent principle. A digital image processor enables a purely geometrical conversion of the map-consistent representation from above provided by said radar equipement into a corresponding image with a centered perspective projection and with a quasi-pilot vision. The invention is used when aircrafts and helicopters fly under bad visibility conditions or with no visibility at all.
