🚨🚨 New paper alert! 🚨🚨 We demonstrate the capabilities of using 94 GHz radar for mapping glaciers, analyse its theoretical performance and showcase some new results from mapping a glacier calving front. Lots more future work to do, check it out below! 👇👇

New AOG paper! “Glacier monitoring using real-aperture 94 GHz radar” by William Harcourt, Duncan Robertson, David Macfarlane, Brice Rea, Matteo Spagnolo, Douglas Benn, Mike James ➡️ doi.org/10.1017/aog.2023.30 @PhysAstroStAnd @UoAGeosciences @StAndrewsSGSD @LancsUniLEC @egg_igs
Figure 1. Close-range sensing continuum illustrating the trade-off between sensor operating frequency, angular resolution (calculated from Eqn (1), where λ is taken to be the centre wavelength of the defined frequency range and D is set constant at 400 mm), and sensitivity to atmospheric obscurants. Lower frequency radar systems are sub-divided into ‘low-resolution radar’ (1–8 GHz) and ‘medium-resolution radar’ (8–18 GHz). Low-resolution radar image is taken from Noferini and others (2009) and medium-resolution radar image is taken from Werner and others (2008).
