【 摘 要 】

Because Modtran software is not convenient to connect with other software programs, a fast algorithm for infrared transmittance in marine environment was established. The relevant meteorological parameters were obtained by actually measuring the marine environment of a certain sea area. The suitable parameters of Modtran to calculate the infrared transmittance of 3∼5μm and 8∼12μm at different distances were selected. Using the exponential function relationship, this paper constructed a fast algorithm in 3∼5μm and 8∼12μm infrared transmittance of marine environment. The comparison between the fast algorithm and the Modtran calculation shows that the maximum error of the 3∼5μm infrared transmittance calculation method is only 2.16%, and the maximum error of 8∼12μm is 0.16%. The formula of the fast algorithm has high precision and can meet the requirements of fast calculation of infrared radiation transmittance.
