Abstract : In this report, we consider the capabilities of a millimeter-wave radar to make atmospheric air flow measurements relevant to naval operations. The measurements could provide data that may be used to generate a map of the turbulent air flow fields in the vicinity of aircraft and aircraft carriers and to characterize the prevailing atmospheric turbulence. One application of these types of measurements is for improved safety of carrier based takeoff and landing. For both fixed wing aircraft and rotorcraft, takeoff and landing are two of the most hazardous operations. Data from measurements of the complex airflows surrounding ships can be used to determine operational envelopes, more efficiently space incoming aircraft, and can be used in conjunction with simulations to inform and influence ship design. Another application is for high-energy laser propagation. Various adaptive optics schemes have been developed in order to compensate for the deleterious effects of atmospheric effects on laser propagation. Accurate knowledge of the level and type of turbulence along the laser path could be used to inform an adaptive optics system.
