- W621504237 abstract "An analysis of the conning function to isolate and define the decisions that must be made to avoid collision at sea is described, with details given for the dynamic, legal and human factors aspects. From these studies new Look-out Assist Devices (LAD) have been developed. The part of the system which is based on radar input (RADAR-LAD) employs a small low-powered transmitter and simple receiver to detect a target as it crosses either of two preset range guard rings. When an intruder crosses each ring, sound and visual alarms are given and the bearing of the intruder is indicated. The acoustic section of the system, known as Hearing LAD also contains automatic alarm circuits and is able to discriminate the type and status of intruding vessels by analyzing the received sound, fog-horns, whistles, bells, etc, in a visual manner. A 20 db to 35 db improvement over the unaided human look-out is anticipated." @default.
