Near-Field Reflectivity and Antenna Boresight Gain Corrections for Millimeter-Wave Atmospheric Radars

Millimeter-wavelength cloud radars operating at Ka band and W band are popular atmospheric research tools because they are compact, have low prime power requirements, and are highly sensitive to small hydrometeors. In order to maximize sensitivity, ground-based systems use large diameter high-gain a...

Description
Summary:Millimeter-wavelength cloud radars operating at Ka band and W band are popular atmospheric research tools because they are compact, have low prime power requirements, and are highly sensitive to small hydrometeors. In order to maximize sensitivity, ground-based systems use large diameter high-gain antennas. However, these antennas have substantial far-field distances as large as several kilometers.
