Abstract: A novel method of generating artificial scintillation noise is developed andused to evaluate occultation rates and false positive rates for surveys probingthe Kuiper Belt with the method of serendipitous stellar occultations. Athorough examination of survey design shows that: 1 diffraction-dominatedoccultations are critically Nyquist sampled at a rate of 2 Fsu^{-1},corresponding to 40 s^{-1} for objects at 40 AU, 2 occultation detectionrates are maximized when targets are observed at solar opposition, 3 MainBelt Asteroids will produce occultations lightcurves identical to those ofKuiper Belt Objects if target stars are observed at solar elongations of: 116deg < epsilon < 125 deg, or 131 deg < epsilon < 141 deg, and 4 genuine KBOoccultations are likely to be so rare that a detection threshold of >7-8 sigmashould be adopted to ensure that viable candidate events can be disentangledfrom false positives.
