摘要：
Two new methods for modelling Kolmogorov phase fluctuations over a finite aperture are described. The first method relies on the incorporation of subharmonics in order to model accurately the low frequencies of the Kolmogorov spectrum. The second method provides a less accurate, but much faster method for simulating thc Kolmogorov spectrum by using a midpoint displacement algorithm used in computer graphics.
