Electromagnetic scattering by turbulent systems is reviewed via an operator formalism with emphasis on possible diagnostic schemes. It is pointed out that in principal both spatial and temporal behavior of fluctuations wavevector and frequency can be determined. Noting that in Born approximation the calculation of total scattering to all directions is independent of orderliness of array, absolute cross-sections are obtained. Using a spectral function thought to bear some relevance to hydrodynamic turbulence, absolute differential cross-sections are obtained for gases argon and plasmas gas seeded with a discharge plasma. Numerical results are presented for optical, infrared and microwave scattering. Possible detection schemes are discussed. Author
