  • In this paper, the ballistic trajectory model of cone-shaped spatial target is introduced. The RCS expression versus cosine of the aspect angle is derived based on the aspect angle expression of a precession target. The frequency transmission characteristic of RCS versus cosine of the aspect angle and the frequency characteristic of cosine of the aspect angle are analyzed. The frequency characteristic of RCS sequence is presented. Then a new method of estimating the precession cycle using the frequency characteristic is presented. Finally, a simulation result shows that the algorithm is effective.
