AI Technical Summary
Technical Problem
Existing radar track initiation methods are prone to forming false tracks in cluttered environments, and machine learning and deep learning methods require additional information or are not suitable for deployment on embedded devices, resulting in unreliable track initiation.
Method used
A track establishment method based on DBSCAN and PCA is adopted, and density clustering and principal component analysis are performed using the spatial information between point tracks to form reliable tracks.
Benefits of technology
The probability of generating false tracks under clutter conditions is greatly reduced by 77.5%, which improves the reliability of track initiation.

Abstract
The invention discloses a track establishment method and device based on DBSCAN and PCA, and belongs to the field of radar data processing, and the method comprises the steps: A, after starting, setting DBSCAN and PCA parameters; b, receiving Kth frame data, and normalizing the Kth frame data; step C, carrying out DBSCAN clustering on the residual point set; and step D, performing PCA operation on the clustered target electric set to form a track. According to the method, a reliable track can be formed in real time under the clutter condition only by depending on space information between trace points.
