The invention discloses a tomographic SAR three-dimensional imaging method based on atom norm minimization. The method comprises the following steps: constructing an atom set and an atom norm of a complete tomographic SAR observation signal; constructing an atom set and an atom norm of the incomplete tomography SAR observation signal; according to the constructed atom set and atom norm of the complete chromatography SAR observation signal and the incomplete chromatography SAR observation signal, constructing a chromatography SAR imaging model based on atom norm minimization; and constructing a positive semidefinite programming solution of the atom norm optimization problem according to the tomographic SAR imaging model and the positive semidefinite programming theory, and realizing SAR three-dimensional imaging by using the positive semidefinite programming solution. According to the method, the atomic norm minimization method is used for chromatography SAR inversion, and compared with ...
