<p>PURPOSE:To track a mobile while taking account of the experiential decision of an operator by detecting only the azimuth and distance as status amounts, filtering the detected data and estimating the motion model of a target in real time while furthermore allowing an operator to select required information arbitrarily from indicating information including error information required for deciding the state of mobile. CONSTITUTION:The system for tracking a mobile 1 comprises a filtering unit 4 including a plurality of filters 40-1... 40-n having different motion models for filtering signals received from a sensor group 2 including a plurality of sensors 20-1... 20-n, a target estimation processor 5 for deciding the motion model of the mobile 3 based on the information therefrom an I/O processor 6 for controlling and generating the information to be displayed on an output unit 8, and an input unit 7 through which an operator sets various conditions. The processor 5 employs a system for making a decision based on the variation rate in the covariance of estimated error as a reference for deciding the motion model. The operator sets the output conditions arbitrarily at the I/O processor 6 and the moving state of the mobile 1 is displayed.</p> |
