摘要

Abstract

Ship stealthiness,as a crucial evaluation metric,requires accurate measurement of the radiated noise level during ship navigation by sonar equipment.Since the vessel acts as a volumetric source,its radiated noise spectrum typically exhibits a broadband continuous spectrum plus line spectra.Consequently,meeting measurement requirements necessitates that the sonar array for radiated noise measurement must achieve constant beamwidth across the required bandwidth to guarantee accuracy in full-bandwidth measurements.A constant-beamwidth beamforming method based on a V-shaped nested array is proposed in this paper.This method ingeniously utilizes the inherent"port-starboard ambiguity"characteristic of linear arrays to form a V-shaped configuration.A constant-beamwidth beamforming method with higher measurement gain is achieved that utilizes the characteristics of nested linear arrays and controls the beam width by adjusting the included angle.Finally,computer simulation experiments verify the correctness of the proposed method.Compared with the traditional nested linear arrays,it resolves the"port-starboard ambiguity"limitation of linear arrays while achieving higher spatial array gain,providing an improved measurement technique for underwater vehicle radiated noise measurement.
