Analysis of estimating radar targets maneuver parameters methods

When the radar is in operation, it is required to track and evaluate the trajectory parameters of radar targets (RT) of various types. In some cases, the RT movement may deviate from a pre-accepted physical model, that is, it may contain a maneuver. For such maneuvering RT, estimation of the trajectory parameters is also required, however, this estimation is complicated by the factor of unknown maneuver parameters. The delay in detecting the RT maneuver relative to its start directly affects the resulting accuracy of estimating the RT's motion parameters (position and velocity). This article discusses the main estimating RT maneuver parameters methods, provides a classification of these methods, and for most of them, an estimate of the maneuver detection time is obtained by modeling. The method with the shortest maneuver detection time has been identified.
