함정 표면 적외선 신호에 대한 해양기상 영향분석

Abstract

A study on the IR(InfraRed) signature of a naval ship has been performed using well known IR signature analysis software, ShipIR/NTCS. Variations of the IR signature radiated from skin of a naval ship have been investigated according to the monthly averaged marine climate conditions. An unclassified destroyer model with and without applying the washdown system was applied to compare the influence on the signature under the background changes. The marine background models were created from the observed data by a buoy of Korea Meterological Administration(KMA). The sensitivity of the ship signature against the climate variables such as air temperature, sea temperature, relative humidity has been studied as well. Simulation results show that the seasons which appear extreme(max, min) skin signature are highly dependent on if the washdown is applied or not. The sensitivities by the air temperature and the sea temperature for a dry-ship reversed by applying the washdown system. the monthly averaged marine climate conditions.
