Comparative assessments of accuracy of angular coordinate measurement in on-board radar when using α - β filter and modifications of Kalman filter
Engineering Education # 12, December 2010
In modern on-board radars equipped with phased antenna array (PAA) the automatic tracking mode of several targets is designed upon the principle of discrete autotracking system. In this case there is a task to optimize the period of each target contact upon the number of targets / autotracking accuracy criterion. In the case of traditional approach the summary error of target coordinate estimation is treated as a random value comprising two components – dynamic component, connected with errors of prediction of a target motion and the fluctuation component, conditioned by measurement errors. Hence it follows the necessity to select the period of discrete multitarget tracking.
