Abstract
A radar with 3-D capability comprises a conventional 2-D radar with a height finding attachment. More particularly, a height finding antenna is mounted on the back surface of the conventional 2-D antenna reflector and points in a direction 180.degree. offset in azimuth from the direction of the 2-D antenna. An r-f transmitter with a linear frequency modulated output is coupled to the height finding antenna and controlled by a transmit control based on target range and azimuth data provided by the 2-D radar. The height finding pulse compression receiver also responds to this target information as well as the height finding return radar signal and extracts height information which is then made available to a suitable display.
