Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0042] Such as figure 1 As shown in Fig. 1, an underwater sensor network target tracking system includes a land network part and a water network part.

[0043] The water area network part includes a plurality of underwater target tracking clusters 1 and a surface processing center 2; each underwater target tracking cluster 1 includes a plurality of underwater sensor nodes 3 and a cluster head node 4, the underwater The sensor node 3 collects the radiation noise of the underwater target, obtains the target orientation information and transmits the information to the cluster head node 4; the cluster head node 4 receives the target orientation information transmitted by the underwater sensor node 3, and uses the corrected time delay The self-adaptive UKF-PF algorithm estimates the target state and uploads the target state information to the surfa...

Abstract

The invention discloses a target tracking system and a target tracking method for an underwater sensor network. The target tracking system comprises a land network and a water area network, wherein the water area network comprises multiple underwater target tracking clusters and a water surface treatment center; and the underwater target tracking clusters comprise multiple underwater sensor nodes and a cluster head node. A target state is tracked in combination with an adaptive UKF (Unscented Kalman Filter) and a PF (Particle Filter) on the basis of correcting signal acquisition time delays of the sensor nodes. The tracking error caused by different sources of signals acquired by the sensor nodes at the same moment is reduced by correcting the time delays, so that a target can be more reliably tracked; and the adaptive UFK automatically adjusts a system noise weighing coefficient according to target maneuvering situation to more properly describe a practical target motion state, so that the shortcoming of inaccuracy of target maneuvering of a target motion model is overcome, an important function with more posteriori information is provided for the particle filter, the particle degeneracy is reduced, and the tracking precision is improved.

Description

technical field [0001] The invention relates to a sensor network system, in particular to an underwater sensor network target tracking system and method, and belongs to the technical field of underwater sensor network information processing. Background technique [0002] The ocean accounts for two-thirds of the earth's surface area and is of vital importance to the survival and development of human beings. At present, human beings' understanding and development of the ocean is only in its infancy. How to understand the ocean more deeply and use ocean resources more rationally is a matter of far-reaching significance. With the continuous maturity and development of land-based wireless sensor networks, underwater sensor networks, as an extension of land-based wireless sensor networks to underwater, are also developing. The underwater sensor network provides a more comprehensive and profound way to understand and use marine resources. Underwater passive target tracking has br...
