The invention relates to means of hydro-acoustics for investigation of surface of sea bed. Information complex consists of the left and the right sides of hydro-locator of side survey, profilograph, device for connection and device for processing and representation of information, set of features makes it possible to provide compatibility of high-frequency propfilograph and hydro-locator of side survey of information complex by means of compensation of effect of high frequency section of emission of profilograph to high-frequency section of reception of the hydro-locator of side survey, this takes place in area of mutual overlap of characteristics direction of hydro-acoustic transformers (see fig. 3). At that the devices of the time automated control of amplification (TACA) make it possible to adapt the levels of the received echo-signals in amplification sections of the hydro-locator and high-frequency channels of propfilograph by distance of radiation, and the adders 0 by direction (the left/right side) of radiation of the bed surface. The invention provides decrease of hydro-acoustic effect of high-frequency sections of profilograph on echo-signals in receiving section of the hydro-locator of side survey. |
