The Prediction of Civil Engineering Problems in the Arctic by Means of Dual-Channel I-R Scanning and Aerochrome Infrared Photography

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 qualif...

Description
Summary: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.
