Abstract

A slow scan radar signal is converted from a polar coordinate format to a cartesian coordinate format to permit the radar signal to be displayed on a television type display device. The radar signal, in analog form, is converted to a digital signal, placed in a memory to permit readout of the data in a cartesian coordinate format and converted from a digital to analog signal which may then be applied to the television type display device.
