Using navigational data, algorithms are defined for atmospheric absorption compensation by range dependent contrast enhancement, debanding by sensor response equalisation, and signal to noise enhancement by summation of image sub-sequences. Improved signal to noise is demonstrated by application to time sequences of infra-red images. Registration accuracy is examined as a function of range.
