Taeangun is a small peninsular district located on the west coast of the main Korean peninsula. To the west, it faces with the yellow sea while its east side is bordered with the main land Korea. This area is well known to have 1) busy mid and high altitude air traffic routes between Korea and neighboring countries and 2) complex and rapid changes in its atmospheric characteristics that tends to reduce the performances of mid infrared (IR) surveillance equipment looking at the aerial targets. In this conference, we report a progress of our study on atmospheric radiative transfer characterization of a coastal interface area, as a precursor to the main study for Taeangun, by using a black body and a mid IR camera. Mid-wave IR camera used are the model X8500 and SC7600 with a lens assembly of 200mm focal length from FLIR® Systems. A blackbody of 7 inch in aperture with the uniformity of ±0.010℃ and emissivity of 0.97±0.02 is used as the target to be measured. The camera and the target blackbody are stationed at the distance of 0.73km to each other. The target was observed across the mid IR wavelength range. In this report, we summarize the current progress of the simulation of atmospheric transmission characterization and of the analysis result of experiment data.
