A navigation method for submarine detection based on magnetic signal continuation algorithm

Abstract

The invention provides anantisubmarine detection machine navigation method based on magnetic signal continuation algorithm for submarine detection, and belongs to the field of the submarine detectionor antisubmarine detection machines and antisubmarine detection indicators. The antisubmarine detection machine navigation method comprises the steps that firstly a magnetized submarine is equivalentto a magnetic doublet, and submarine signals of a present complete ship route represented by a combination of orthogonal basis functions are acquired; an antisubmarine detection indicator composed ofthree single-direction vector magnetic-field measuring probes is mounted on the antisubmarine detection machine in an orthogonality mode; on the present ship route, submarine detected signals are acquired using the antisubmarine detection indicator, prolongation is conducted on the submarine detected signals, thus the prolonged submarine signals of the present complete ship route are acquired, orientation of the submarine is calculated, and the present ship route of theantisubmarine detection machine is further updated; and the process is repeated until the antisubmarine detection machine is located over the submarine, and the navigation ends. According to the antisubmarine detection machine navigation method based on the magnetic signal continuation algorithm for the submarine detection,real-time location is conducted on the submarine through the antisubmarine detection machine, thus the route is continuously corrected, and the antisubmarine detection machinedirectly flies to the submarine, flying distance of the antisubmarine detection machine is greatly reduced, and submarine detection time is shortened.

Description

technical field [0001] The invention relates to the field of submarine detection or submersible detectors and submarine detectors, in particular to a navigation method for submarine detectors based on a magnetic signal continuation algorithm. Background technique [0002] In order to strike a submarine, it is necessary to effectively locate the submarine. The sonar method currently used can detect the sonar emitted or reflected by the submarine through the sonar measuring equipment located in the water, so as to judge whether there are submarines around and locate the submarine. This method has a long detection distance and mature technology. However, since sonar is used to detect signals in water, it is suitable to install it on ships, but it is not feasible to install it on attack aircraft. [0003] The magnetic submarine detection method is to use the principle of magnetic anomaly detection technology to detect magnetic submarines, that is, because the steel structure of...

This overcomes the disadvantages of using the previous magnetic target detection method to navigate the submersible, and it is necessary to wait for the aircraft to fly away from the submarine to obtain a complete signal before the submarine can be located.
