Disclosed is a three-dimensional radar apparatus comprising a radar transmitting/receiving unit (14), a three-dimensional polygon-generating unit (16), and a three-dimensional graphics unit (18), wherein a radar transmitter/receiver (20) outputs signals concerning orientation information, distance information, and reception intensity information on the basis of a radio wave reflected from a target, and a scan converter (22) is used to convert the signals concerning the orientation information, the distance information, and the reception intensity information into two-dimensional radar image data composed of two-dimensional rectangular coordinates and brightness information of each of picture elements. The two-dimensional radar image data is also inputted into the three-dimensional polygon-generating unit (16) to perform polygon-generating processing on the basis of the two-dimensional rectangular coordinates and the brightness information of each of the picture elements. Three-dimensional radar image data is prepared in the three-dimensional graphics unit (18) on the basis of obtained polygon-based information, and it is accumulated in a frame memory (24). Thus, a three-dimensional radar image is displayed on a display device (26). <IMAGE> |
