As radar photos present knowledge otherwise than a standard optical digital camera, the photos are normally black and white when they’re acquired. Through the use of a expertise that aligns the radar beams despatched and acquired by the instrument in a single orientation – both vertically or horizontally – the ensuing knowledge may be processed in a manner that produces colored photos reminiscent of the one featured right here. This system permits for a greater distinction of options on the floor.
