Embodiment Construction

[0052] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0053] like figure 1 As shown, a dual-synchronous underwater cooperative target tracking and positioning method described in the present invention completes the tracking and positioning of underwater targets through the cooperation of the underwater acoustic buoy measurement array and the measurement mother ship, wherein the underwater acoustic buoy array realizes the target cooperation Acoustic signal reception, calculation of related time delay value and measurement of buoy position, and return the time delay value result and buoy position to the measurement mother ship, and the measurement mother ship receives the returned data of the buoy through the erected antenna, and then transmits the data through the main control computer The base stati...

Abstract

The invention relates to a double-synchronous underwater cooperative target tracking and positioning method, which includes a sea surface hydroacoustic buoy measurement array and a measurement mother ship. The positioning is completed through the following steps: deploying the sea surface hydroacoustic buoy measurement array; underwater targets sending out double synchronous cooperative acoustic signals ;The measurement mother ship receives the return data of the sea surface hydroacoustic buoy measurement array through the erected antenna, and completes the matching of the target delay period, the combined solution of the target position, and the solution of the spherical equations through the base station composed of the main control computer and the shipboard integrated processor The method can effectively reduce the frequency band resources required for multi-target underwater tracking and positioning, and reduce the If the small positioning system conflicts or interferes with the frequency bands used by other installed equipment, it can reduce the risk of engineering practice; save design costs; effectively reduce the amount of calculation, effectively reduce the power consumption of hardware circuits, and reduce the volume of installed 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, ...
