| description | The embodiment of the invention relates to the technical field of radar detection, in particular to a three-dimensional scattering center position parameter calculation method based on a target RD image sequence. The embodiment of the invention provides a three-dimensional scattering center position parameter calculation method based on a target RD image sequence, and the method comprises the steps: observing a target through a plurality of radars, and obtaining a multi-angle RD image sequence; wherein the RD image sequence comprises a plurality of scattering centers; extracting a micro-motion linear velocity and a micro-motion linear acceleration of each scattering center from the RD image sequence; calculating the micro-motion angular velocity of each scattering center based on principal component analysis and a characteristic decomposition method; and calculating the three-dimensional space position of the scattering center by a linear least square method according to the micro-motion linear velocity, the |
