To this end, models predicting these contributions have been developed. The objective of the present paper is to assess the performance of the bathymetric uncertainty prediction model for Phase Difference Bathymetric Sonars (PDBS) which is an interferometric sonar. Two data sets were acquired with the Bathyswath-2 system with a frequency of 234 kHz at average water depths of around 26 m and 8 m with pulse lengths equal to 0.0555\u00a0ms and 0.1581\u00a0ms, respectively. The comparison between the bathymetric uncertainties derived from the measurements and those predicted using the current model indicates a relatively good agreement except for the across-track distances close to the nadir. The performance of the prediction model can be improved by modifying the term addressing the effect of footprint shift, i.e., spatial decorrelation, on the bottom due to fact that at a given time the footprints seen by different receiving arrays are slightly different.<\/jats:p>","DOI":"10.3390\/rs14092011","type":"journal-article","created":{"date-parts":[[2022,4,24]],"date-time":"2022-04-24T00:45:21Z","timestamp":1650761121000},"page":"2011","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Assessing the Performance of the Phase Difference Bathymetric Sonar Depth Uncertainty Prediction Model"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0340-1718","authenticated-orcid":false,"given":"Tannaz H.","family":"Mohammadloo","sequence":"first","affiliation":[{"name":"Acoustics Group, Faculty of Aerospace Engineering, Delft University of Technology, 2629 HS Delft, The Netherlands"}]},{"given":"Matt","family":"Geen","sequence":"additional","affiliation":[{"name":"ITER Systems, 3 Rue du Lac Mont-Cenis, Batiment Est Supernova Savoie Technolac, 73290 La Motte-Servolex, France"}]},{"given":"Jitendra","family":"S.
