Zusammenfassung:The invention discloses a dynamic platform foresight super-resolution imaging method based on sub-blind-control detection SAMP. The method comprises the following steps: carrying out range filtering on a baseband echo signal; calculating a foresight scene scattering coefficient observation value by using an acceleration phase compensation function and an envelope dechirp function according to the filtering signal; constructing an over-complete dictionary matrix; performing foresight super-resolution imaging by using an improved SAMP algorithm according to the foresight scene scattering coefficient observation value and the over-complete dictionary matrix; according to the algorithm, sparseness estimation is carried out based on a divide-and-conquer method, and a foresight scene signal is reconstructed based on sparseness; wherein the two functions and the over-complete dictionary matrix are constructed based on a single-channel foresight scanning imaging geometric model facing a dynamic platform; the model in
