%X Ideal knife-edge image and real remote sensing images were selected as the original image, and a series of degraded images were obtained through applying a various of radiation and geometric resampling operation on these original images. Then the MTF (modulation transfer function) evaluation was performed using the original image and all of degeneration images based on slant edge method. Experiments show that, in evaluating MTF of the imaging system, proper radiation resampling operation can be performed on the image for the visual effect, which will not affect the imaging system MTF, but the geometric resampling can seriously affect the MTF of imaging system.
