Title: Fixed beam radar with range light display

Abstract: A radar principally for use on small vehicles such as sail boats, utilizing a fixed antenna which provides a continuously forward looking beam and which provides a range display only. Utilizing digital techniques, the video representing radar echoes is gated in proper time sequence corresponding to target range to a series of indicator lights. These indicator lights each represent a different target range, and thus provide a display indicating the range at which various targets forward of the vehicle are located.
