Abstract

The present invention provides a maneuvering object tracking method based on the Gaussian filter. The method comprises the following steps: selecting an optimal filtering model and the length of the filter memory according to whether a target happens the maneuvering or not; generating an overall observation matrix which comprises the following steps: generating a transfer matrix, generating a measurement matrix; and finally establishing the overall observation matrix. The maneuvering object tracking method based on the Gaussian filter overcomes the defect that the current tracking filter method has bad high-speed and high maneuvering target so as to improve the tracking precision and the tracking stability.

Description

technical field [0001] The invention belongs to the technical field of maneuvering target tracking, in particular to a Gaussian filtering-based maneuvering target tracking method. Background technique [0002] Since the beginning of the satellite era in 1958, Kalman filtering has been recognized as a good method for radar tracking and filtering engineering in the past 50 years, because this method uses an iterative recursive algorithm to realize tracking filtering and has a significant advantage of small amount of calculation. In radar engineering practice is widely adopted. However, in the case that modern aircraft, missiles, satellites and other combat weapons and platforms generally have high speed and high maneuverability, Kalman filtering still has shortcomings in tracking accuracy and stability. Gaussian filtering has many good characteristics in tracking filtering engineering, and Gaussian filtering is not easily disturbed by instability, so it is especially suitable...
