THE STUDY OF THE RECEPTION TRACT OF A FLEXIBLE EXTENDED TOWED ANTENNA AT A CIRCULAR OVERVIEW

The question of the formation of the directivity characteristic in the path of receiving flexible long towed antenna with a circular review has been reviewed. The intensity of the signal was determined taking into account the influence of the environment on its propagation. The main parameters of the environment and the signal affecting on the intensity value are analyzed. The directivity characteristic of a flexible long towed antenna for different compensation angles is described. Accounting for the directional properties of the antenna is introduced by multiplying the directional characteristic on the signal intensity. Energy summation was produced over the entire frequency range of the antenna. The classification signs are determined: the acoustic length and asymmetry of the signal. This signs are the basis by which will be decided: is the signal came from a group or a single object. The acoustic length and asymmetry of the signal are calculated for different angular positions by two methods: the area method and the probabilistic method.
