Abstract:
The feasibility of detecting massive ice in permafrost by sensing the associated surface thermal anomalies with an airborne synchronous dual-channel infrared I-R line scanner is discussed in this first semi-annual report. Three broad areas of research are involved a the determination and qualification by both mathematical modeling and ground truth field studies of significant parameters useful in detecting any thermal anomalies caused by near surface ice in permafrost, b the modification of a standard quantitative I-R scanner to synchronously sense and record radiation emitted in the 4.5-5.5 and 8-12 micron bands, and c the processing electronically of the recorded information to obtain the ratio and product imagery used to delineate the thermal anomalies sought.
