Investigation into the utility of using CFAR cluster size information in target track association

During CFAR processing of low-resolution-radar data (e.g. from yacht navigation systems), the target is represented by a cluster of range-azimuth cells. The centroid is usually passed to the tracking system, however information on the size of the cluster, and therefore extent of location error is available from the CFAR. The main hypothesis of this presentation is "would the use of the cluster bounding-box 'corners' allow better plot-to-track associations when compared to using the region centroid alone?".
