Factors affecting the quality of formation and resolution of images in remote sensing systems

The article deals with the factors affecting the quality of formation and resolution of an image in a high-resolution scanner (HRS). It is shown that the stabilization parameters of a spacecraft (SC), on which a HRS with a charge-coupled device operating in time delay integration mode (TDI-CCD) is installed, signifi­cantly affect an image distortion, namely its blurring, and this blurring increases when the number of inte­gration lines goes up in the TDI sensor.
