Abstract:
It is supposed that the targ et’s velocity be invariable in a line, init ial v alues of the trajectory can be obtained from tw o valid point s of the t rajectory at least by the usual methods. A new parameter est imation method based on the mult-i ang le informat ion for a f ly ing object is presented. Using the method, init ial values of the t rajectory can be gotten w ith only one distance under the limitat ion of laser dynamic echo w ave ratio, therefore the response t ime of the fire control system can be shortened. T he mult-i angle values can be passively measured by optical inst ruments, and only one active laser-echo ought to be obtained in theory, then the measure inst rument w ill be concealed to a certain ex tent .
