Title: Ice thickness measuring method for sea ice
Inventor: ISHIHARA KOJI
IPC: G01S15/88
Filed: 1985-11-26
Abstract: PURPOSE:To attain a measurement continuously with good precision by processing the indicated value of a microwave range finder and the indicated value of an ultrasonic range finder and measuring the thickness of sea ice. CONSTITUTION:Pulses of a microwave 6 are emitted toward a sea water surface 4 on which sea ice 10 floats and then the microwave 6 having passed through the sea ice 10 is reflected by the sea surface 4 and returns to the position 9 of a transmitter-receiver. A gap h2 is found from the time interval and the speed of the microwave 6 in air. Further, the pulses of an ultrasonic wave 7 are emitted from the position 9 toward the sea surface and then the wave is reflected by the sea surface 5 and returns to the position 9. This wave is received to find an interval h1 from the time interval and the speed of the ultrasonic wave 7 in air. Further, those two measurement results are transmitted to an arithmetic means 3, which finds the thickness T of the sea ice from (h2-h1=T).
