Abstract

Generally, brightness of midcourse missile from reflecting sunlight are dependent on the sunlight direction and observation direction. The calculating method of direction Correlation Coefficients is different to difform objects. This paper introduces a simple way through vector integral to calculate the Correlation Coefficients. As an example, the midcourse missile with cylinder shape is used to illustrate the process of vector integral method. The results by this way are same as that indicated in literature. The characteristic of vector integral method is processing in the right-angle coordinate so that doesn’t be limited by geometric form of the space objects. The rule of selecting a system of coordinates is ease to calculate. According the selected system of coordinates and the right-angle integral surface (xoy, xoz or yoz), the expression of integral is different .
