Air target sensor management method based on target threat degree

Abstract

The invention discloses an air target sensor management method based on target threat degree. According to the method, after the actual state of the target is measured and obtained, the threat degreeof the target position and the information gain of each sensor on the target measurement are calculated; more sensor resources are required to ensure the tracking precision and the continuous trackingcapability for targets with relatively high threat degree or with abnormal flying tracks; according to the method, the sensor distribution based on threat degree and information gain is achieved, andmore appropriate sensor resources can be distributed to targets with high threat degree according to calculation of multi-target threat degree and information gain, so that the tracking precision ofthe sensor network on a high-threat degree target when multiple targets are tracked is improved, and the sensor network achieves higher use efficiency. The method has great application potential and value in various military and civilian fields such as missile interception, regional target monitoring, air traffic control and the like.

Description

technical field [0001] The invention belongs to the fields of air multi-target tracking, situation assessment and air traffic control, and in particular relates to an air target sensor management method based on target threat degree. Background technique [0002] In recent years, with the use of various advanced sensors and new fighter jets, unmanned aerial vehicles, missiles and other weapons, the problems involving perception systems and sensor networks that need to be solved on the modern battlefield are increasing, such as missile defense, situation estimation, over-the-air vision, etc. distance detection etc. On the one hand, a larger number of sensors is conducive to obtaining higher-precision estimates through information fusion, and on the other hand, it also brings new problems, such as transmission problems in multi-sensor networks and energy consumption problems. At the same time, complex battlefield environments and more targets also require more efficient senso...
