- Product description
-
The system allows users to configure parameters such as the sampling rate and gain levels for high- and low-acoustic channels, and to customize either self-contained storage or real-time target-detection feedback modes. The onboard non-acoustic sensors can measure array depth, pitch, roll, and heading angle. With its compact array architecture, the system can be deployed for extended periods even on small unmanned marine platforms, such as AUVs and wave gliders.
Key features
• Low self-noise
• Low power consumption
• Supports two output modes: self-contained and real-time detection.
• Supports users in developing signal processing programs through secondary development.
• Ultra-large capacity storage
• Built-in high-precision pressure and attitude sensors
• Various housings, supporting full ocean depth
• The host computer interface is simple and easy to operate.
• OEM customized versions available upon customer request.Typical applications
