摘要: By performing rotation and translation operations, a radar display converts a radar signal to radar image information expressed in a three-dimensional orthogonal coordinate system with horizontal, vertical, and depth coordinates related to a certain viewpoint. Terrain and target information is converted to the same coordinate system and combined with the radar image information, producing a realistic three-dimensional display. Clipping is performed in the depth direction to eliminate portions of the radar image disposed behind terrain or target images. Terrain and target images disposed behind the radar image are reduced in intensity, but not clipped. Perspective projection and zoom transformations may also be carried out.
