Section 7 Overview of Processing Algorithmsb = B α ( i, j,k,g ) + B ( i, j,k,g ) B ( i, j,k,g )Equation 7.2-9NL+PDWhere, B α ( i, j,k,g ) is offset of the exposure coefficient pulse, and B PD( i, j,k,g ) is PD darkcurrent.c) Calculation of the correction coefficient ‘c’‘c’ is a dummy pixel output, and it is calculated for every band. It takes an average of dummy pixels in onescene, however, the number of standardized lines is defined as one scene.c = C (j,l) l: line number Equation 7.2-10d) Radiometrically corrected processingExpressing the sensor output by O, and the amount of the incidence radiation by L, Equation for theradiometric correction is expressed as follows using coefficient ‘a’, ‘b’ and ‘c’ calculated from abovesections.O − b − cL = Equation 7.2-11a7-16
