Abstract:

A theoretical study has been made of the scattering of electromagnetic waves from both underdense and overdense turbulent low altitude rocket plumes. The analysis considers a number of parametric assumptions about the nature of the turbulence, namely, type of correlation function, correlation lengths, isotropu of turbulence, finite conductivity and plume intermittency. The analytical results have been applied to the cross section of both an underdense and overdense plume at 65,000 ft altitude. The most important result is that the theoretical cross section can be large for some reasonable assumptions about the nature of the plume turbulence.
