Abstract

The invention relates to a tracking and positioning method four double-synchronization underwater cooperative targets, wherein the system according to the method comprises a sea-level underwater acoustic buoy measurement array and a measurement mother ship. The tracking and positioning method finishes positioning through the following steps: laying the sea-level underwater acoustic buoy measurement array; transmitting a double-synchronization cooperative acoustic signal by underwater targets; receiving returned data of the sea-level underwater acoustic buoy measurement array by the measurement mother ship through a mounted antenna, and finishing target time delay period matching, target position combined resolving, spherical surface equation set solved value returning and target position depth interval by a base station which is composed of a master control computer and an on-ship comprehensive processor, thereby realizing resolving and display to the target position, and realizing tracking and positioning for each underwater target in an area. The tracking and positioning method has functions of effectively reducing frequency band resource required in tracking and positioning multiple underwater targets, reducing confliction or interference between frequency bands used by a positioning system and other mounted equipment, reducing risk in engineering practice, saving designing cost, effectively reducing calculation amount, effectively reducing power consumption of a hardware circuit, and reducing size of the mounted equipment.

Description

technical field [0001] The invention relates to a target tracking and positioning method, in particular to a dual-synchronous underwater cooperative target tracking and positioning method, and belongs to the technical field of underwater target tracking and positioning. Background technique [0002] With the advancement of human exploration and development of the ocean, the underwater activities carried out by humans are becoming more and more frequent, and more and more equipment and equipment in various fields such as scientific research, resource development, engineering construction, and national defense and military are deployed underwater. How to track and locate these underwater targets, especially the tracking and positioning of multiple targets in an area has become a hot spot in the research of underwater positioning technology. Due to the difficulty in purely passive underwater detection and positioning, and the high risk of project implementation, at this stage, ...
