    Effects of Atmospheric Refraction on an Airborne Weather Radar Detection and Correction Method by Lei Wang, Ming Wei, Tao Yang, Ping Liu

    Published 2015-01-01
    “…This study investigates the effect of atmospheric refraction, affected by temperature, atmospheric pressure, and humidity, on airborne weather radar beam paths. Using three types of typical atmospheric background sounding data, we established a simulation model for an actual transmission path and a fitted correction path of an airborne weather radar beam during airplane take-offs and landings based on initial flight parameters and X-band airborne phased-array weather radar parameters. …”
