A terrain mapping radar utilizes two sets of separately processed radar signals, each provided by a coherent pulse doppler synthetic aperture signal processing channel connected to and for processing the signals received from a selected one of a pair of vertically displaced antennas of the type utilized in phase interferometer radars. The invention provides depression angle, and therefore elevation information from the processed signals on a cell by cell basis, uniquely, for each range/doppler cell of each of the processing channels. The invention eliminates azimuthal errors which result from the ambiguity of the range/doppler annulus, and provides a useful map metric: elevation.
