Using transport theory, calculations were made for the radar cross section of an underdense turbulent wake in the limit when the scale size of the turbulence is larger than the signal wavelength. It was found that for bistatic scatter the first Born approximation is valid, even if the wake is many photon mean-free paths in extent. However, neither the Born approximation nor the modified Born approximation is valid for the nonstatic radar cross section when the wake is many photon mean-free paths in extent. In this case a modified result, derived in the report, must be used.
