An experimental study of sediment discrimination using 1st and 2nd echoes
Analysis of Roxann seabed classification data, at 24 kHz and 200 kHz, using co-located echosounders is presented. Timeseries backscater data gathered at the same time as the Roxann data has also been anal~sed using variations on the integration schemes used. Variation due to both the ,frequencj difference, depth dependancy and processing scheme are discussed.
