Method of determining the vertical angle of arrival of a signal to a towed array

Method of determining the vertical angle of arrival of a signal to a towed array Abstract The paper demonstrates the possibility of determining the vertical angle of arrival of a signal to a towed horizontal array. The estimate accuracy is determined by the size of the change in the horizontal angle of direction to the signal source during aperture synthesis. The method is checked by the results of a field experiment. Under conditions of finding the receiver array in a shadow zone with respect to the emitter and scatterer, we reveal the fact of formation of a uniray signal in the waveguide with the angle of reflection of the signal from the bottom at an angle on the order to 50° toward the horizontal. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acoustical Physics Springer Journals

Abstract

Abstract The paper demonstrates the possibility of determining the vertical angle of arrival of a signal to a towed horizontal array. The estimate accuracy is determined by the size of the change in the horizontal angle of direction to the signal source during aperture synthesis. The method is checked by the results of a field experiment. Under conditions of finding the receiver array in a shadow zone with respect to the emitter and scatterer, we reveal the fact of formation of a uniray signal in the waveguide with the angle of reflection of the signal from the bottom at an angle on the order to 50° toward the horizontal.
