The aim of the paper is to analyze data obtain during sounding of the Gdansk Bay by means of the parametric sonar. The accuracy of the sea bottom structure investigation needs the correct configuration of research equipment and the proper calibration of peripheral devices (GPS, heading sensor, motion sensor MRU-Z and navigation units) which provide necessary data to bathymetrical measurement system enabling its work with whole capabilities. Parametric sub-bottom profiler device deliver two types of data which include different information: envelope and pure echo signal without processing. The first is used to present echograms in real time and the second one store data which can be analyze in post-processing software. Differences in results will be presented and discussed. Criteria that were taken into account during the determination of the measurement areas and the selection of the different configurations of the software, according to the information that should be obtained from trials will be described. Complementary information can be obtain by means of processing the data using procedures offered by Matlab, which allow a clear presentation of the results in 3D, with the possibility of using accurate methods of measurement. The consideration will be illustrated by echograms taken in the natural conditions.
