| Abstract: | In this paper relationship between the optical transfer function of sea water and the distribution of natural radiance field in the sea is simply and directly determined based on the transform model of the sea radiance transfer. The variance of the angle spectrum of the sea radiance field is analysed. A new simple m thpd of estimating the distribution of the sea radiance field and measuring the optical transfer function of the sea water is proposed. The method is perfectly suitable for the atmospheric circumstances. |
