(PDBS) system in shallow waters are presented in the article. The measurement results were
compared with the theoretical calculations for sonar system accuracy and international
standards for hydrographic surveys. The proposed formulas enable to assess
a priori sonar system performance using system quality factor (SQF), which takes into
account influence of variable environmental conditions and auxiliary sensors on depth
accuracy in a real-life scenario. The proposed SQF can be used in survey planning process
to predict the swath width.
