Abstract

The invention provides a multi-group target tracking system and method. The system comprises a data obtaining unit, which is used for obtaining state data of multiple groups of targets at one moment;a data modeling unit, which is electrically coupled to the data acquisition unit and is used for establishing a state model based on the acquired state data; a data prediction unit, which is electrically coupled to the data modeling unit and is used for estimating the state model by means of a gamma Gaussian inverse Wishart probability hypothesis density filtering algorithm and generating prediction data; and a data updating unit, which is electrically coupled to the data prediction unit and is used for introducing the prediction data to update the state model. The system and method are to solve the group maneuvering problem and the model probability prior solidification problem in the prior art.

Description

technical field [0001] The present application relates to the field of target measurement, in particular to a multi-group target tracking system and method. Background technique [0002] In many tracking scenarios such as radar target monitoring and multi-target formation tracking, the tracked object is usually composed of a series of spatially adjacent targets with similar motion patterns, and such problems can be summarized as group target tracking problems. The existing technology has the problem of modeling the form of group motion, which cannot solve the problem of group maneuvering and does not update the model probability, and there is a problem that the model probability is a priori solidified. Contents of the invention [0003] In order to solve the problem of group maneuvering in the above-mentioned prior art and the problem of prior solidification of the existence model probability, the present application provides a multi-group target tracking system, the syste...
