Abstract

This study numerical demonstrates the principle of parameter design of the two vertical source-receiver arrays system for separation of eigenrays in shallow water multipath environment. The two arrays performed transmission and reception of acoustic pulse signal repeatedly, and use a double beamforming algorithm to obtain arrival angle and launch angle of each eigenray simultaneously. Comparison of parameter design is made between the situations that the range between the two arrays are 100m and 1km. The result show that the arrival angle, launch angle and arrive time of adjacent eigenray are close to each other as the source-receiver range increase, and the selection of operation frequency, element spacing, array length of the two arrays system should make the system to have a narrower main lobe angle.
