FLUCTUATING INFRARED RADIATION FROM HOT JETS, BOUNDARY LAYERS AND SHEAR LAYERS.
Abstract
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.
