REMOTE ICE-THICKNESS MEASUREMENT METHOD, REMOTE ICE-STRENGTH MEASUREMENT METHOD, REMOTE MEASUREMENT METHOD, REMOTE ICE-THICKNESS MEASUREMENT DEVICE, REMOTE ICE-STRENGTH MEASUREMENT DEVICE, AND REMOTE MEASUREMENT BODY

WIPO Patent Application WO/2016/098350

A1

Provided are a remote ice-thickness measurement method, a remote ice-strength measurement method, a remote measurement method, a remote ice-thickness measurement device, a remote ice-strength measurement device, and a remote measurement body, whereby the true thickness or strength of ice can be measured without contact therewith at any location by remotely measuring an apparent ice thickness including accumulated snow on the top surface of the ice using an electromagnetic induction sensor, remotely measuring the thickness of the accumulated snow using electromagnetic waves, and calculating the true thickness or strength of the ice on the basis of the apparent ice thickness and the thickness of the accumulated snow.
