Instruments and Methods: A Low-Cost Glacier-Mapping System
An old portable 60 MHz radar has been upgraded with a new digital data-processing and acquisition system and a new antenna construction enabling a fast and low-cost installation on a Twin Otter aircraft. Augmented by a laser altimeter and kinematic global positioning system (GPS), the system has the...
