Titel
Using lateral length measurements in GMTI convoy tracking
Abstract
This contribution deals with tracking of convoys moving on ground by airborne GMTI radar. A technique based on generalized power estimators using multiple beams is used to estimate the lateral length component of an unresolved convoy. In combination with the conventional range measurement, the full length information can be obtained in case of a linear convoy. The main focus of this paper is the exploitation of this attribute information in order to improve the tracking process. The Bayes algorithm based on our earlier work is improved and incorporated into a JPDAF framework to deal with multiple targets. The processing of Doppler measurements is also included. Numerical results are presented based on a simulation scenario.
