On the Synthesis of a Moving Target's Positions

This paper deals with the synthesis and forecasting of a moving target's positions through measurements of the miss distance and the positions of the theodolite. A method for calculating the coefficients of an interpolation polynomial through resolving the set of equations is proposed. Compared with Lagrange's, the interpolation polynomial obtained by this method is simpler. Based on the interpolation polynomial and the deviations in azimuth angle and elevation angle obtained at non?integral multiple sampling periods the deviation at integral multiple sampling period can be written as a polynomial with time-delay as parameter. An identification algorithm of the time-delay is given in this paper, and thus the problem in the synthesis of a moving target's positions is solved.
