In shallow waters stripes information collected from the process of being prosecuted by the environmental impact would cause physical location is the base areas,and the vibrations spread, the center o(f CMP )coordinates the gun and a position to receive jointly determine the wave.some positions are not accurate will be given the CMP some mistake,and CMP binning had been superimposed disorders;it will also lead to receive the offset is from there,at the correct mistakes and affecting the superposition of information.Therefore,by the state project "863 program underwater high precision the development of the positioning system",using visual c++ and qt technology developed,development high-precision the second orientation software ",the entire process of the implementation of the visual.This paper mainly the results are as follows:1.In traditional the second position on the basis of the software to a method of intensive study by the shallow water at the wave of the relocation technology to attend to the cause of the motion.2.For practical information to the problems of energy than the algorithm used to improve,and optimize the technological research and improve the accuracy and precision to pick up and was beginning to pick up the comprehensive research module.3.A comprehensive study of the three dimensions relocation of methods and techniques, Raised the point of wave and three-dimensional mathematical model; presents the corresponding key technology solutions and measures to reduce the focus on how to locate the process of error, raise receiver's calculate precision. 4.Integration from early loot algorithm and localization algorithm and the corresponding accuracy control algorithm, and developed and algorithm related graphic display function;5.Use two of the hundredth meridian receives a sea of information on the functionality and performance test results indicate that the method correctly,the development of the software function completely,high precision,the speed automatically.
Keywords/Search Tags:The location accuracy, receiver relocation, automatically to the position, first-break picking, shallow waters
