Abstract
A method for cross calibration of different sensors onboard same satellites is proposed. BRDF of the standard plaque for the reference of the surface BRDF measurement is measured and corrected in the proposed cross calibration. Furthermore, difference of the spectral responses of the sensors as well as differnt Instantaneous Field of View: IFOV are taken into acount in the cross calibration. As the results from the experiment with ADEOS/AVNIR and OCTS, it is found that the proposed method shows a good cross calibration between both and works for evaluation of NEdR or Signal to Noise ratio: S/N. Through a comparison of the evaluated S/N with the previously reported S/N from NASDA, it is also found that the proposed method is appropriate for the S/N validation.
