This research is sponsored by the Royal Observatory of Hong Kong and fulfills part of Agreement ROC IV 7-92 VI. Per subsection 12.3 of the Agreement, findings may only be distributed for scientific, academic, and research purposes. Any other use must be authorized by the authors and the Royal Observatory of Hong Kong. The particular formulation of the stochastic backscatter was suggested to us by Alex Praskowski. The authors also wish to thank the SGI Corporation for a loan of their Power Challenge computer, which was used for the high-resolution experiment. We also thank William Anderson for his support in porting the code to the SGI machine.
