ABSTRACT
This chapter discusses the first and second problems of target track parameter estimation definition. It describes the main results of filtering theory and extrapolation methods with reference to signal reprocessing problems in complex radar system (CRS). The chapter explores the representation form that is understandable to designers and engineers of signal processing algorithms, and computer architecture systems and other experts exploiting CRSs for various areas of application. It argues that the target track model combined with the model of measuring process forms the model of united dynamic system representing a process subjected to filtering. Radar target tracking is performed by the use of the echo signal reflected from a target illuminated by the radar transmit pulse. Dynamic errors arising owing to mismatching between the target moving hypotheses can be neglected as a consequence of the narrow approximated part of the target track.
