Brown Motion Diffusion Model for Chaff Clouds

  • Received Date: 07 Jul 1999

  • The diffusion model and numerical simulation model for chaff clouds are modeled on the assumption that the speed of air where chaff locates is a Winner random process and the mass of chaff is zero so it can trace the atmosphere speed very well. For the diffusion model and numerical simulation model, the numerical character of chaff clouds during diffusion is obtained. Comparing numerical character of above two models, it shows that the variance of atmosphere motion must be modified so the time step used in numeric simulation has no effect on numerical character of chaff clouds. The numerical simulation result agreed with this analysis.
