Abstract : A radar is disclosed that obtains three-dimensional radar images of targets for target identification at tactically useful ranges. Images are generated with the radar in a target angle and range tracking mode. The image is a plot, display or recording of position of target scatterers in range and two orthogonal gross-range dimensions. Range resolution is obtained by generating synthetic range profiles from the monopulse sum channel echo voltages which results from transmitting a strepped frequency waveform. Cross-range resolution is obtained by similarly processing differential cross-range error voltages of the echoes seen at the output of two orthogonal channels of a wideband monopulse receiver.
