The principle of operation of the device

The result of the work of the sub bottom profiler is a profilogram, which shows the structure of the bottom relief and the geological section of the sediment thickness in the form of a graphic image. It is possible to use a profiler in the range of sea depths from 1 to 400 meters with a signal penetration of up to 40 meters into a given pound (depending on the composition of the soil, frequency and noise level).This profiler uses a signal with a primary frequency of 100 kHz. The secondary frequency (4 - 15 kHz) should be selected based on the followingcriteria: - the best signal-to-noise ratio; - maximum penetration depth; - High resolution.
