AN EVALUATION OF PERFORMANCE AND EFFECTIVENESS OF A MAN OVERBOARD DETECTION AND LOCATION SYSTEM

This project deals with development of a man overboard detection and location system for use on documented vessels. Preliminary research indicated that radio (RF) systems offered more potential than sonar. The concept for use of the RF system involves a small transmitter the size of a metal tape rule to be worn by each crewman while on deck. In the event of a fall overboard, the unit automatically begins transmitting which actuates an alarm and serves as a homing device for rescue. The major part of this effort was the demonstration of successful reception of an RF signal from a small prototype man overboard type of transmitter located at varying depths in fresh and salt water. Range for fresh water tests was greater than one mile. Range for salt water was considerably less. A program for development of an operational man overboard system for Great Lakes, inland waters/rivers, and deep sea vessels is discussed. (Author)
