Abstract: In this paper the defects in interline CCD matrix were studied, which appear as a result of its irradiation with high-energy protons. Defects were studied in different operation modes: in frames mode and in time delay and integration (TDI) mode. By using a special organization of TDI mode we were able to localize defects in vertical register with a precision of one pixel. The dependence of the defects behavior on different system parameters was also studied, such as: temperature, exposure time in frame mode, exposure time of every step of integration in TDI mode, charge storage time in vertical register and number of integration steps in TDI mode. Also a method of removal of the influence of these defects directly during flight tests was developed and tested.

Key words: interline CCD matrix, time delay and integration mode, high-energy protons, Earth remote sensing.
