Abstract
An active microwave method is investigated for measuring surface air pressure by using radar reflections at frequencies around 53-55 GHz O2 bands. The numerical simulation results for homogeneous backgrounds show that with an airborne radar working at these O2 absorption bands, the rms errors of the radar surface pressure estimations with 15-dB signal-to-noise ratio can be as low as 4-7 mb. A radar system that covers these wavelengths will have great potentials for weather observations and other meteorological applications.
