Abstract :
In order to improve the velocity and accuracy of pointing algorithm used for antenna, a novel algorithm based on the quadratic curve theory is presented in this paper. According to theoretical value of pointing algorithm and antenna´s states, the antenna is located by action of servo system. Compared with the step searching algorithm, the new proposed algorithm has several advantages, such as: little time in searching, fast speed, and high precision. Experiment results show the validation and speediness.
