Abstract : Side-Looking Airborne Radar (SLAR) provides an all weather, all light level medium for imaging large areas of saline and fresh water ice. This report evaluates the use of SLAR imagery for determining winter sea and lake ice paremeters and compares winter sea ice pattern 'keys' with summer pattern 'keys'. The report also makes a preliminary evaluation of the effects of snow cover on the SLAR imagery and on the interpretation of ice conditions. In addition, an interpretation technique is developed which permits the interpreter to analyze ice environments to a greater degree than is possible through the use of image pattern keys. The study points out the requirement for additional research to correlate lake ice image patterns with age, thickness, condition, and snow cover parameters through a combined remote sensor and on-ice study.
