ABSTRACT:
A memory for a coordinate converter stores, for each azimuth at which information from an information source may be received in a polar coordinate system, the incremental X and Y coordinate values, .DELTA.X and .DELTA.Y, for an incremental change in range along the azimuth. For each azimuth these incremental coordinate values .DELTA.X and .DELTA.Y are retrieved from memory and entered into summing devices which are incremented respectively by .DELTA.X and .DELTA.Y for each increment of range. The integers of the values of the summing devices represent X and Y coordinate values in a rectangular coordinate system and may be utilized to address an information reception device such as a random access memory.
