Overview
TR-VH04 is a cylindrical 3D vector hydrophone designed for low-frequency underwater acoustic measurement. It captures three-axis particle velocity signals to realize passive azimuth estimation for low-frequency sound sources.
Working frequency band covers 15–2000Hz, suitable for shelf sea low-frequency noise monitoring, marine seismic survey, low-frequency target detection and underwater acoustic experiment. It features stable directional performance with lateral rejection ratio ≥20dB and low asymmetry.
Cylindrical form Φ86×480mm, air weight 3.4kg, near-neutral buoyancy (1.05–1.1g/cm³ in water), which helps reduce flow noise during long-term subsea deployment. It adopts SEACON HUML-12-BCR watertight connector, and supports connector, cable and mechanical customization.
