Low speed formation target tracking method based on formation pattern

Abstract

The invention discloses a low speed formation target tracking method based on formation pattern, and the method mainly solves track cross and data redundancy problems which easily present in measurement and track association process in prior art. The technical scheme comprises: formation partition and formation association are separately performed on targets, and the track initiation of the formation targets is completed; after the above, the distance and angle from each target in the formation to a formation center form a shape description matrix of a formation to describe the formation shape; the measurement of the each target in the formation is allocated according to the formation shape description matrix, the measurement corresponding to the track in the formation is obtained, smooth filtering is performed on the measurement to obtain an update state of the measurement; after the above, the formation shape is updated based on the formation pattern description according to the update state, and the tracking of the formation target is completed. According to the invention, the accuracy and processing efficiency of the frame target tracking are improved, and the method can be used for radar data processing.

Description

technical field [0001] The invention relates to the technical field of radar data processing, and mainly relates to a slow formation moving target tracking method, which can be used for tracking formation targets on the ground and sea. Background technique [0002] Target tracking is based on the target information detected by the radar signal processing system, using certain means to interconnect and filter the data, suppress various errors in the measurement process of the target, and obtain the position and motion state of the target at a specific moment, that is, the velocity. Accurate estimates of size and orientation. In military operations, troops or ships are generally dispatched in formation, which can improve combat efficiency and safety, and is also an important means of penetrating radar, so the tracking of formation targets in the surveillance area is an urgent research for the tracking system one of the subjects. [0003] Formation target is a special kind of...

Problems solved by technology

This type of method takes the target group as the extended target, thereby avoiding the data association problem of formation members. The disadvantage is that it only considers the formation as a special case of the extended target, and does not use the characteristic information such as the current situation and size of the formation, and cannot be applied to formations with variable formations. In the case of high computational complexity and poor tracking accuracy
