The invention discloses a target tracking method and system based on elliptic Hough transform. The method comprises the following steps: acquiring first measurement data of a radar station; converting the first measurement data into second measurement data in a preset coordinate system, wherein the preset coordinate system has a preset elliptic equation, and the preset elliptic equation has target parameters; determining detection point data according to a preset quantization parameter, the preset elliptic equation and the second measurement data; and determining a tracking trajectory of the target according to the detection point data. According to the invention, the acquired first measurement data of the radar station is converted into the second measurement data under the preset coordinate system for processing, the preset elliptic equation conforming to the trajectory target trajectory is combined, and the detection point data is determined according to the preset elliptic equation, the preset quantization parameter and the second measurement data so that the tracking trajectory of the target is determined. And a trajectory target can be detected and tracked. The method can be widely applied to the technical field of radars.
Description
technical field [0001] The invention relates to the technical field of radar, in particular to a target tracking method and system based on elliptic Hough transform. Background technique [0002] The Hough transform was first applied to line detection in images, and was later introduced into the field of radar data processing, mainly used for track initiation and track-before-detect (TBD) anti-stealth. Nowadays, the track detection of targets for radar data processing usually uses the classic straight-line Hough transform, and the straight-line Hough transform is only suitable for track detection in a short period of time, but for ballistic targets, their trajectory is a space curve. And its radar cross section (Radar Cross Section, RCS) can be as small as 0.00009 at least. Therefore, the linear Hough transform is difficult to obtain a better TBD detection effect, and it cannot effectively detect and track ballistic targets. Contents of the invention [0003] In view of ...
