MULTIRANGE FLEXIBLE EXTENDED TRAILING ANTENNA Russian patent published in 2007 - IPC G01S7/52 

FIELD: the invention refers to information transmitting lines in hydro acoustic apparatus of hydrophone direction finding.

SUBSTANCE: the multirange flexible extended trailing antenna with lines of transmission of information of a hydro acoustic station has a number of united in a single hose of linear equidistant subantennas. Each of them has hydro acoustic transformers, whose phase centers are located at a distant equal to the half of the length of wave of the upper frequency of the range of the subantenna, preliminary amplifiers and lines of transmission of information to aboard apparatus. At that each transformer and amplifier and line of transmission are connected in-series forming a receiving channel, and each subantenna i out of M subantennas where i= 1,2,...M-1, is divided on equidistant groups with a number of receiving channels in the group Ki,i+1 where Ni- a number of receiving channels of the subantenna, where Ki,i+1 - relation of the upper parts of subantennas i and i+1, summing amplifiers are switched at the output of the groups. The outputs of the amplifiers are connected with the inputs of the aboard apparatus of processing of receiving channels of the subantenna i+1.

EFFECT: reduction of receiving channels and decrease of the length of the antenna of each substance.
