註釋

Fractal geometry can simulate natural topography, creating data that can be used in sonar models as realistic ocean bottom features. An algorithm using recursive subdivision, or midpoint replacement, is used to create the fractals. The appearance, statistics, and dimension of the fractal can be controlled through the use of variables. The variables control the initial corner values and the amount that each subdivision can vary from the average of its two initial points. The choice of a random number distribution also affects the final fractal. The statistics, fractal dimension, and appearance of data generated by the fractal algorithm are comparable to real data.
