Long Base Line Underwater Navigation System Acoustic Transceiver

This article gives the theoretical and simulation analysis about acoustic signal processing based on Long Base Line Underwater Targets Tracking System, and also gives the design of engineering software and hardware.The main task of acoustic signal processing block is to receive and process acoustic signal. In this article we major in the design of the hardware of the Acoustic Transceiver. The hardware connects the hydrophone with the Communication Module, separated into the analog part and the digital part by HCN. The whole hardware will be controlled by the Communication Module, and be low power consume. And the construct of the optical receiver is analysed and according to the trait of buoy signal processing, the engineering substitute structure-Notch filter and VIFD detector combined signal processing is devised, with detecting and estimating in the same time.In the aspect of engineering devise, the kernel is the design of hardware and DSP signal processing software.
