SAN FRANCISCO VESSEL TRAFFIC SYSTEM TEST OF THE AN/FPS-109 (XN-1) VESSEL TRAFFIC SYSTEM MANUAL RADAR

The report presents the results of engineering tests made on the U.S. Coast Guard Vessel Traffic System (VTS) radars, the AN/FPS-109 (XN-1), which are installed at Yerba Buena Island (YBI) in the San Francisco Bay and at Point Bonita (PTB) overlooking the seaward approach to the Bay. Two types of tests were conducted. The first type consisted of measurements of antenna beam patterns of the YBI antenna, radiated power, transmitter and receiver characteristics, display characteristics, and PTB/YBI data link performance. The second type of tests was concerned with performance measurements and included maximum detection range in clear and clutter environments, coverage as a function of elevation angle, realizable range and angle resolution, and the utility of the various radar and display operating modes.
