Four aspects of the near field infrared background noise problem have been investigated 1 a semi -empirical theory for predicting the levels and spectral distribution of infrared radiation fluctuations from an optically thin hot turbulent flow has been developed, 2 an experimental program has been completed and has confirmed the theory developed by comparing predictions of the broad band rms radiation and spectral radiation with radiometric measurements, 3 a series of flight-regime charts have been derived that show the spectral distribution of the near field radiation, and 4 the dependence of the background noise upon the system optical field has been derived.
