ABSTRACT:
A radar principally for use on small vehicles such as sailboats, utilizing a fixed antenna which provides a continuous forward looking beam and has a dual range display providing range and limited azimuth information. Separate antenna elements are utilized to receive echoes in the paths of left and right radar beams respectively, these left and right beams being slightly to the left and right of the boresight of the radar antenna. Utilizing digital techniques, the video representing radar echoes received in the left and right beams is gated in proper time sequence corresponding to target range, to a series of indicator lights for left and right range display respectively. These indicator lights each represent a different target range and are excited in accordance with video signals received in the left and right beams respectively. The indicator lights vary in their intensity so as to indicate whether targets are to the left or right of the antenna boresight and thus to the left or right of the heading of the vehicle. The indicator lights thus indicate both the range and relative azimuth of targets ahead of the boat.
