Abstract

The invention provides an underwater communication positioning identification integrated waveform optimization method. In order to meet the demand of improving the underwater network situation perception and situation information interaction capability, through analyzing relations between underwater acoustic communication signal waveform parameter and underwater acoustic positioning range fining precision and a network inside member identification probability, the underwater communication positioning identification integrated waveform optimization method and a criterion are brought forward, constraint relations of underwater acoustic communication signal parameters for positioning and identification performance are given, and underwater integrated waveforms are realized through an optimization design method. According to the invention, a conventional communication waveform function can be effectively expanded, the effects of distance-distance positioning and network inside member identification functions are realized while data transmission is realized, an important base is provided for improvement of an underwater multimode network cooperation capability, and technical support is provided for development of an underwater network information system.

Description

technical field [0001] The invention belongs to the technical field of underwater network information system application. Background technique [0002] Since electromagnetic waves are severely attenuated when propagating in water, and sound waves are the only form of energy known to mankind so far that can travel long distances in water, detection, communication, positioning, navigation and identification in the ocean are mainly realized by using sound waves. Therefore, the research on the integrated waveform optimization of underwater communication positioning and identification mainly focuses on the research on underwater acoustic communication, positioning and identification. [0003] Underwater acoustic communication technology has experienced the development process from analog communication stage to digital communication, and it is mainly divided into two categories: non-coherent modulation and coherent modulation. Non-coherent modulation has obvious advantages in ant...
