一种基于水压场阵列传感器的舰船定位方法
A Ship Location Method Based on Water Pressure Field Array Sensor
摘要
Abstract
Ship water pressure signals have characteristics that are difficult to imitate.This paper uses water pressure field ar-ray sensor to collect signals,uses cross correlation calculations to calculate time delays,improves traditional time of arrival local-ization methods,and applies them to water pressure field localization.A target localization method for array processing of ship water pressure signals is proposed.Under the traditional time delay localization method,the step iterative processing method is improved to eliminate errors,increase the number of sensors,and can solve the overdetermined equation when the signal propagation speed is unknown.Through multiple simulation experiments,the average positioning error in the near field environment is about 1.7 m,and the maximum error is 2.91 m.Using the ship water pressure signal to locate a ship is feasible.关键词
