A system is disclosed for mapping terrain from a vehicle in which the area to be mapped is resolved into strips by rotating a narrow fan shaped beam with the velocity vector of the vehicle the approximate center of the scanning system. The reflected energy is multiplied by a reference signal to generate a doppler spectrum which is resolved into elements of area along the strip determined by the antenna pattern by applying the spectrum to a bank of graduated filters. The beam of an indicating device is swept along the radius of the device with the output of the filters used as an intensity control.
