An aero-optical heat radiation noise correction method, comprising the following steps: firstly, pre-processing a degraded image to obtain a multi-scale degraded image set; then, according to the multi-scale degraded image set, taking the last scale estimation result as the next scale estimation initial value to obtain an update and iteration process for an optimal solution to finish deviation field estimation on an original scale; and finally, restoring the degraded image according to a deviation field estimation value of the original scale to obtain an aero-optical heat radiation noise correction image. The present invention also relates to an aero-optical heat radiation noise correction system, comprising a multi-scale processing module, a deviation field estimation module and an image restoration module. The method and system effectively solve the problems of a poor correction effect, a high method complexity and being unable to perform heat radiation noise correction in the image level in the existing me
