Abstract：Aiming at those shortage that photoelectrical tracking equipment of high accuracy in dynamic real-time measure?ment and small angle of field,those lead the equipment is difficult in target acquisition independently,so it requires outside target guidance during in target tracking test. Then the paper analyzes the characteristics of the target motion and tracking principle. Based on these analyses,the paper derives the polynomial path fitting and data extrapolation model combined with the classical polynomial fitting,and discusses the models'application of target guidance through real time calculation of the relative spatial parameters. Com?bined with the actual test data,it analyzes the accuracy of the data,and calculates the estimation error of azimuth and pitch calculat?ed by predicted data. All these prove the method can be used to solve the actual test and the data accuracy may meet the use require?ments after processing.
