An integrated method combining underwater target positioning and remote control telemetry data underwater acoustic network transmission

Abstract

The invention relates to an integrated method integrating underwater target positioning and remote control and telemetering data underwater acoustic network transmission, which uses equipment including a plurality of positioning submersible buoys, a measured target platform, a wireless relay buoy and a shipborne display and control platform, wherein the plurality of positioning submersible buoys sink to the bottom and arranged to be a subsea measurement matrix, and then measurement is carried out on the position of the positioning submersible buoy matrix. A measured target sails in a measurement region formed by the subsea measurement matrix, the measured target platform sends acoustic inquiry signals continuously in an evenly spaced mode, a positioning submersible buoy within the operating range receives the inquiry signals, waits for fixed delay time and replies answering signals, the measured target platform receives the answering relay signals, carries out self-position calculation according to signal detection results and sends combination of a calculation result and a depth measurement result to the nearest positioning submersible buoy in an underwater acoustic communication mode, the nearest positioning submersible buoy transmits the combination of the calculation result and the depth measurement result to the shipborne display and control platform, and the underwater position of the measured target can be monitored in real time on the display and control platform.

Description

technical field [0001] The invention relates to an integrated method for underwater target positioning and underwater acoustic network transmission of remote control and telemetry data, which is suitable for precise positioning and tracking of underwater targets, underwater remote control and telemetry, underwater monitoring and underwater acoustic communication. Background technique [0002] Hydroacoustic positioning technology refers to the use of sound waves emitted by the target (including its own radiation noise or actively emitted acoustic signals) or the echo signal of the target to determine the existence of the target. The underwater acoustic positioning method mainly refers to a method that can be used for precise navigation and positioning in local areas. The underwater acoustic positioning method is a method composed of a matrix composed of multiple primitives (receivers or transponders). The distance between primitives in the matrix is ​​called the baseline leng...
