Abstract:
A three-dimensionally designed display radar comprising:a radar transmitting/receiving section for deriving an orientation signal, a distance signal, and a reception intensity signal concerning a target respectively;a display unit;a display memory provided with a memory cell corresponding to each of picture elements on said display unit, for reading image data stored in said memory cell to supply it to said display unit;a two-dimensional coordinate converter for converting said orientation signal and said distance signal into XY coordinate values to be used for two-dimensional screen display;a two-dimensional image memory for storing said reception intensity signal as two-dimensional image data in said memory cell designated by said XY coordinate values;a three-dimensionally designed coordinate converter for converting said orientation signal and said distance signal into XY coordinate values based on a perspective projection drawing method, and converting said reception intensity signal into a signal for indicating a height of said target with a length of a straight line; andan image controller for selectively outputting, to said display memory, one of or both of said two-dimensional image data outputted from said two-dimensional image memory and three-dimensionally designed image data outputted from said three-dimensionally designed coordinate converter on the basis of an instruction of an operator, wherein:any one of or both of a two-dimensional image concerning said two-dimensional image data and a three-dimensionally designed image concerning said three-dimensionally designed image data are displayed on said display unit on the basis of control made by said image controller.
