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 -36.5 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 height above sea level based on the altitude of the radar system which was measured using a handheld GPS. The rapidly changing surface texture of the lake has resulted in considerable scatter in the Gaussian fit and therefore calculated height of the lake. A moving average (we recommend a window size of ~50 samples) can be used to reduce this and resolve fluctuations in lake level.
