Abstract : The patent describes a method and apparatus for measuring, with radar, the intensity of atmospheric turbulence and/or distinguishing between the radar reflections from clear air turbulence and those produced either by clouds or by the occurrence of a large vertical gradient in radar refractivity. Two or more conventional microwave radars operated simultaneously at different preselected frequencies, transmit and receive reflected energy from a selected atmospheric volume. The received signals are processed to obtain a comparison of the signal amplitudes or intensities from the radars and the data derived from this comparison is used to indicate the intensity of detected clear air turbulence and to distinguish such turbulence from other atmospheric phenomena; e.g., clouds, etc. which also produce radar reflections.
