Software Defined Sonar
Sonar Prototype Rapid Development & Verification Platform;
Underwater Acoustic DAQ & Signal Processing Board , FPGA + Dual-Core NPU Edge AI Platform
This acoustic acquisition and processing board is a modular embedded computing platform integrating dual-core CPU, NPU and programmable FPGA. It serves as the core digital front-end for underwater acoustic systems and is built as a sonar prototype rapid development & verification platform. It supports hydrophone array signal acquisition, waveform preprocessing, DDS excitation signal generation and edge-AI analysis.
The platform supports dual operating systems: Embedded Ubuntu for algorithm development and data logging, and RTOS for low-latency synchronous control. Abundant peripheral interfaces and open C/C++ & Python SDK significantly cut down the development cycle for underwater acoustic prototypes and commercial systems. Receiver and transmitter modules can be expanded on demand.
Important Note: This product is a bare circuit board module. It does not include pressure housing, waterproof encapsulation, hydrophones, transducers or power amplifiers. Pressure-resistant housing is available as a separate customization item.
