Statement

Raw radar returns have been converted to range using standard FMCW processing. The width of the radar beam (3 degrees) coupled with the oblique viewing angle (antennas at -43 degrees from horizontal) results in a broad return spanning many range cells from the surface of the lake. A Gaussian fit has been made to this return, and the range to the lake taken as the range of the peak of the Gaussian. Ranges have been corrected for viewing geometry and converted to lake surface level relative to mean surface level. Positive values therefore represent higher than average levels. Radar returns from stationary clutter at the margins of the lake have been suppressed using a Moving Target Indication technique described fully in https://doi.org/10.1029/2018GL079177.
