Embodiment Construction

[0079] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0080] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0081] In addition, in describing the present invention, the terms used are for the purpose ...

Abstract

The invention discloses a radar target tracking method and system. The method is applied to target prediction and tracking in two modes, including the Long mode in which the target is predicted and tracked by using the historical track information of the target and the target is predicted by using the historical track information of the target. Short mode for tracking. Judging target maneuverability based on target size and historical trajectory information, and determining the historical track of the target in the Short mode; through the historical track of the target, determine the predicted speed of the target in the two modes; according to the predicted position of the radar carrier and the target in the two modes The predicted speed in the two modes determines the predicted azimuth and distance of the target in the two modes; the predicted wave gate in the two modes is determined through the predicted azimuth and distance of the target in the two modes; the predicted wave gate of the target point in the Long mode If the matching fails, then match the predicted wave gate of the target trace in Short mode, and update the target information when the matching is successful.

Description

technical field [0001] The invention relates to the technical field of radar data processing, in particular to a radar target tracking method and system. Background technique [0002] Radar target tracking refers to the optimal estimation of the target position and state by the radar target tracking system using the measured values ​​of the current moment and the past moment. Traditional radar target tracking methods can accurately predict the position and state of regular moving targets such as uniform speed or uniform acceleration, but cannot accurately predict targets with strong maneuverability, resulting in unstable or lost target tracking. Contents of the invention [0003] In order to solve the problem of unstable or lost tracking of highly maneuverable targets, the object of the present invention is to provide a radar target tracking method and system. [0004] The present invention provides a radar target tracking method, which is applied to target prediction and...
