| description | The invention discloses a fast analysis method for coherent characteristics of a network radar target. The fast analysis method is mainly used for judging whether coherent synchronization processing can be carried out on a multi-base radar or not. A target to be detected is divided into a plurality of array elements, and each array element contains N parameter sets. The target excites induced current under irradiation of plane electromagnetic waves emitted by the radar and generates a scattered field, induced current, excitation and an impedance matrix of the scattered field corresponding to a to-be-analyzed receiving radar node are obtained, a scattering matrix equation is constructed, a characteristic mode is used as a global basis function, and the scattering field is obtained; and carrying out rapid dimension reduction on the scattering matrix equation to achieve the target of rapid electromagnetic calculation. Echo data are obtained after the scattering coherent matrix is solved, and coherent characteris |
