Problems solved by technology

Among them, the advantages of autonomous navigation are all-weather, full space, and high concealment, but the disadvantages are high cost and cumulative increase of navigation errors; non-autonomous navigation has high positioning accuracy, no initial alignment, and positioning accuracy has nothing to do with the voyage, but it is easy Interference, poor concealment, and additional auxiliary systems are required; the matching navigation method using the inherent physical characteristics of the earth has the advantages of high autonomy and strong concealment, but the positioning accuracy and navigation application range are limited by the integrity and accuracy of the prior data map , difficult to apply in unknown environments, such as geomagnetic matching navigation

Embodiment Construction

[0027] The purpose of the present invention is to address the deficiencies of existing navigation methods and the defect that geomagnetic matching navigation relies too much on prior databases, and according to the distribution characteristics of geomagnetic parameters, a geomagnetic bionic navigation method based on evolutionary strategy segmented search is proposed. From the perspective of biological magnetic trend sensitivity, the navigation process is summarized as a process of continuous convergence of various magnetic parameters to the target point parameters. Through real-time collection of geomagnetic parameters, the simultaneous convergence of geomagnetic parameters in a local area is taken into account on the basis of the use of evolutionary strategies. Features, dynamically changing the navigation strategy, so as to complete the navigation task efficiently and quickly, has a very good application prospect.

Abstract

The invention provides a segmented search geomagnetism bionic navigation method based on an evolution strategy. A multi-target evolution algorithm is used as a theoretical basis, and on the basis of completing the activities such as homing and migration by drawing lessons from bio-utilization geomagnetism in the nature, starting from the bio-magnetism trend sensitivity angle, the geomagnetism bionic navigation method based on the evolution strategy and independent of a prior data bank is provided. The method has the advantages of being all-weather, completely autonomous, high in invisibility,free of cumulative errors, suitable for unknown environments and the like.

Description

technical field [0001] The invention relates to a geomagnetic biomimetic navigation method based on segmental search of an evolutionary strategy, and belongs to the technical field of geomagnetic navigation. Background technique [0002] The development of navigation technology is of great significance to the development of military and civilian aspects. At present, according to the different ways of using navigation information sources, navigation methods are mainly divided into three categories: autonomous methods using their own information, non-autonomous methods using external information sources, and matching methods using the inherent physical characteristics of the earth. Among them, the advantages of autonomous navigation are all-weather, full space, and high concealment, but the disadvantages are high cost and cumulative increase of navigation errors; non-autonomous navigation has high positioning accuracy, no initial alignment, and positioning accuracy has nothing...
