Interpretation of SLAR imagery of ice in Nares Strait and the Arctic Ocean / by Moira Dunbar.: DR52-17/10-1975E-PDF

"SLAR imagery of Nares Strait was obtained on four flights carried out in January, March and August 1973 and April 1974 by Canadian Forces Maritime Proving and Evaluation Unit in an Argus aircraft equipped with a Motorola APS-94D SLAR; the March flight also covered two lines in the Arctic Ocean, from Alert to the pole down the 4°E meridian to the ice edge at about 80°N. No observations on the ground were possible, but some back-up was available on all flights from visual observations recorded in the air, and on the March flight from infrared line-scan and vertical photography. The interpretation of ice features from the SLAR imagery is discussed, and the conclusion reached that in spite of certain ambiguities the technique has great potential which will increase with improving resolution. Extent of coverage per distance flown and independence of light and cloud conditions make it unique among airborne sensors"--Abstract, page ii.
