Processing method for multi-target detection, characterisation and tracking and related device

A method for processing measurements obtained by an antenna system at a given time index t, comprising:

• within a first list of clusters, a cluster defined as a set of measurements including temporal characteristics, spatial characteristics and signal characteristics, a cluster being created from a first measurement and evolving as new measurements are produced, predicting, at the time index t, the spatial characteristics of each cluster contained in the first list of clusters as a function of the spatial characteristics of the cluster when lastly updated to form a second list of clusters;
• for each measurement:
• forming a third list of clusters included in the second list, each cluster including the previously predicted spatial characteristics;
• calculating a likelihood score between the measurement and each cluster of the third list of clusters, the likelihood score being calculated from two factors, a first factor being a distance between the measurement and at least one spatial characteristic of the cluster and the second factor being the result of a statistical processing of the characteristics of the cluster;
• selecting the maximum likelihood score;
• comparing the maximum likelihood score with a predetermined threshold:
• if the maximum likelihood score is above the threshold, updating the characteristics of each cluster of the third list of clusters to form a fourth list of clusters integrating the information of the measurement;
• otherwise, creating a new cluster from the measurement and placing the new cluster in the second list of clusters.
