Why is the grazing angle of the acoustic pulse on the bottom so important in Multibeam backscatter, and even MORE important when generating multispectral backscatter imagery? Look at the road…
This tool calculates the nadir size of a multibeam footprint based on Transmit & Receive Beamwidths and the altitude of the sonar above the bottom. If you do not know…
This article, first published in Hydro International in 2012, is still relevant but has a few caveats due to advances in Satellite Based Augmentation Systems (SBAS). In 2012 SBAS corrections…
