摘要：
Statistical properties of the scattered field for a laser altimeter arc considered. Analytical expressions arc developed for the optical field correlation function and intensity correlation function, as well as the correlation degree of intensities of speckle patterns. The relationship between the backscattered signal intensity and the target toughness is analyzed.
