Abstract To compensate the translation motion of precession ballistic targets, the characters of translation and precession are analyzed and it is found out that the precession has the center symmetry character. Using this character, a method based on conjugate multiplication of center symmetry data is proposed to estimate the translation motion of precession ballistic target. The precession motion is canceled out due to the conjugate multiplication and the translation motion parameters can be estimated by the spectral peak position of the conjugate multiplied signal. Therefore, the translation motion can be compensated based on the estimated translation motion parameters. Simulation results verify the validity of the proposed algorithm.
