Abstract

This paper presents a new method of sampling the climatic data for infrared signature analysis. Historical hourly data from a stationarymarine buoy of KMA(Korean Meteorological Administration) are used to select a small number of sample points (N=100) to adequatelycover the range of statistics(PDF, CDF) displayed by the original data set (S=56,670). The method uses a coarse bin to subdivide thevariable space (35=243 bins) to make sample points cover the original data range, and a single-point ranking system to select individualpoints so that uniform coverage (1/N = 0.01) is obtained for each variable. The principal component analysis is used to calculate a jointprobability of the coupled climatic variables. The selected sample data show good agreement to the original data set in statisticaldistribution and they will be used for statistical analysis of infrared signature and susceptibility of naval ships.
