The movement is the main form of movement of the space ballistic target, and the recognition of the inmoving characteristic is the basis for judging the target attribute. By analyzing the echo phase form of a single intake scattering point, a phase recovery algorithm restores the phase change of narrow-band radar echo signal. The recovered phase is analyzed spectrally, so as to estimate the spin and velocity of the target. The simulation results prove the validity of the algorithm and have good robustness.
