Book Description
Airborne radar appears to be the single, most promising sensor for reliable, all-weather detection of icebergs over wide areas. However, current knowledge is inadequate to determine conclusively the optimum system or systems, configuration, and operating precedures. The field program proposed in this report is designed to collect the data that would be required to address this issue.

Book Description
Describes an experiment called Bergsearch '84 in which five airborne radar imaging systems were tested for their ability to detect icebergs in open water off Canada's east coast. Three of the systems were real-aperture side-looking radar and two were synthetic aperture radar. Previous research in radar detection of icebergs is first reviewed. Section II details the experiment planning and the data collection and reporting methods used. Section III analyzes and interprets the data collected. Estimates are given for average detectability of icebergs of various sizes, both in significant wave heights below 2.9 metres and with comparison to available surface and aerial photographic information. Factors affecting detectability are discussed.

Book Description
Desire to improve current airborne iceberg surveillance capability for ice management in support of offshore oil explo ration has raised interest in alternative radar systems. This experiment evaluated two generations of search radar, system designed for military purposes. Search radar designed to oper ate at low altitudes. Rotating antenna allows target to be detected ahead of aircraft so that plane can divert to view & confirm target.

Book Description
During the Spring of 1985, the U.S. Coast Guard R & D Center conducted an open-ocean evaluation of the AN/APS-135 SLAR in cooperation with the International Ice Patrol (IIP). Data were collected to determine the system's ability to detect various surface craft (ranging from a 4-person life raft to a 55-meter ship) and ice targets. The effects on detection performance of target size, range, search altitude, and sea state were evaluated using the experiment data. Search altitudes of 2500 and 4000 feet and target ranges up to 25 kilometers were tested for surface craft. For ice targets, 2500-, 4000-, and 8000-foot altitudes and ranges up to 50 kilometers were used. Analysis of the data indicated that SLAR is capable of detecting icebergs and the 55-meter ship in seas up to 2 meters nearly 100 percent of the time. The smaller targets were detected 40 to 96 percent of the time in seas less than 1 meter and 0 to 65 percent of the time in seas of 1 to 2 meters, depending on target size. Unalerted operators detected 10 to 60 percent few targets than alerted operators depending on target size and sea state. Detection range limits of the AN/APS-135 SLAR for targets larger than the 4-person raft were not identified using the 25-kilometer range scale. (Author).

Book Description
A study has been undertaken to investigate the use of enhancement techniques to increase the radar detectability of icebergs. These techniques will permit more efficient use of iceberg management tools such as support vessels and aircraft. There are essentially two strategies to achieve enhancement available: namely, passive and active. Passive techniques refer to those which increase the icebergs effective echoing area or radar cross-section and include the deployment of reflective material on the iceberg surface as well as a number of reflector configurations based on balloon and kite systems. Active techniques include the use of radar transponders, radio direction finding equipment, radio navigation equipment and satellite tracking systems.
