ABSTRACT:
A warning system that operates with an existing radar system to display on the scope thereof a first pair of traces of adjustable maximum and minimum range defining an early warning collision range, provides a bearing trace through a radar-detected object or target and brackets the object with range lines across an adjustably limited bearing sector while actuating a warning alarm. The system also defines an alarm zone of lesser range than the warning zone and operates to activate a further alarm for any radar-detected object or target therein. Additionally, the system may incorporate a tow warning capability for identifying the straying of a towed barge, for example, from a predetermined tow zone.
