Available in PDF, EPUB and Kindle. Book excerpt: Describes a comprehensive field program undertaken in 1984 to assess the iceberg detection capability of existing marine-type radars. The semi-submersible Sedco 706 drilling platform on the Grand Banks was selected for the trials. It has four radar systems on board, two X-band and two S-band, plus low-noise receivers for increased sensitivity. During the data collection phase, recordings of radar video signals were made for various icebergs, ships, and drilling rigs. Raw video signals from each radar were digitized sequentially and stored on tape for subsequent analysis. Data collected have proven useful in identifying the effect of critical environmental conditions such as ducting and subrefraction, as well as providing valuable information on sea clutter.

This book was released on 1986 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: To thoroughly investigate the iceberg detection capability of shipborne marine radar, a field program was carried out aboard the MV POLAR CIRCLE in the northern area of the Grand Banks of Newfoundland area during April 1985. The data collected is able to provide information on icebergs in sea clutter, emphasizing small icebergs, and to demonstrate the advantages of signal processing to maximize detection capability. The data have been used to validate a radar model that can predict radar performance under a variety of operational and environmental conditions by modifying the input parameters.

Download or read book Bergsearch '84 written by James R. Rossiter and published by Published under the auspices of the Environmental Studies Revolving Funds. This book was released on 1985 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1985 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Enhancement of the Radar Detectability of Icebergs by : Joseph Patrick Ryan
Download or read book Enhancement of the Radar Detectability of Icebergs written by Joseph Patrick Ryan and published by . This book was released on 1986 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
