Self-adaptive active sensor tracking method based on tracking precision and risk control

Abstract

The invention provides a self-adaptive active sensor tracking method based on tracking precision and risk control, and the method comprises the steps: firstly obtaining the parameters and state information of a tracking target through measurement data sampling, and carrying out the evaluation of the threat degree of the target through a dynamic fuzzy Bayesian network (DFBN) method; predicting thethreat risk in combination with the probability that an active sensor signal is intercepted by a tracking target; secondly, evaluating the tracking precision of the active sensor by using the target prediction covariance and the measurement noise covariance; and finally, constructing an efficiency function by fusing the tracking precision and risk control to reasonably allocate the active sensor resources. According to the method, the threat risk assessment method is improved, and the target threat risk is predicted more accurately and reasonably; secondly, the tracking precision and risk control are fused to construct a self-adaptive active sensor tracking method, the method is more suitable for a complex and changeable real environment, and the target tracking capability is improved.

Description

technical field [0001] The invention relates to the technical field of active sensor management in target tracking, in particular to an adaptive active sensor tracking method based on tracking accuracy and risk control. Background technique [0002] With the rapid development of active sensor technology, manufacturing level and computer technology, a multi-active sensor platform composed of various active sensors with different functions is widely used in the tracking tasks of aircraft to targets. With the complexity of the working environment of aircraft and the continuous advancement of science and technology, multi-active sensor platforms are generally installed on modern advanced aircraft, such as synthetic aperture radar, forward-looking infrared radar and electronic, friend-or-foe devices, etc. The introduction of multi-active sensors overcomes the It eliminates the inaccuracy of a single active sensor and improves the robustness of the system, but at the same time how...

AI Technical Summary

Problems solved by technology

[0004] The proposal of the active sensor management algorithm solves the problem of active sensor resource allocation, but whether it is based on tracking accuracy or risk control, it only considers one of the directions, and cannot take into account the needs of the other direction. The complex and changeable actual environment requires

[0005] With the continuous development of science and technology, modern aircraft should have multiple mission requirements such as reconnaissance, tracking, and strike, so the active sensor management algorithm for a single mission obviously does not meet the actual needs
