Data acquisition and analysis of the underwater acoustic signal based on virtual instrument;

Research of noise reduction of underwater acoustic signals based on singular spectrum analysis;

The design of a novel data acquisition and storage system of low frequency underwater acoustic signal;

This paper reviews the existing methods of chaotic signals analysis and puts forward applications of chaos to the identification of underwater acoustic signals.

By using the arithmetic of infomax into the separation of underwater acoustic signals by researching the underwater acoustic signals distributing.

Taking Water Depth Monitoring System for Port Channels as background and in view of the characteristic of acoustic emitted in the research, we take MCU and FPGA as core control units, designed an acoustic signal acquisition and processing system suitable for engineering project which is based on GPS time synchronization technology.

The underwater acoustic signal can cause surface wave motion at the water-air interface and hence modulate the magnitude of the laser beam falling on the water surface.

A research was made on detecting underwater acoustic signals using laser.

The laser detection of underwater acoustic signals exploited a laser receiving technique.

Medium and low frequency underwater acoustic signals detecting with laser interferometry

A new method has been developed to detect real-time underwater acoustic signals with laser and a corresponding test system has been built.

A testing installation established by using the proposed method can detect underwater acoustic signals,which verifies the adequacy of relevant theory and simulation process as well as practicability of the method.
