AB: The success of GPS/GNSS radio occultation in retrieving refractivity profile of high vertical resolution from active limb sounding of the atmosphere has led to the novel concepts of microwave crosslink remote sensing. A microwave crosslink system consists of spaceborne receivers and at least one spaceborne transmitter with frequencies designed to be sensitive to the absorption lines of water vapor and possibly other trace species. Microwave crosslinks can yield high vertical resolution profiles of the atmosphere like GPS radio occultation, but with the much desired ability of retrieving water vapor unambiguously throughout the troposphere. In this work, we discuss a simulation study of the accuracy and vertical resolution of the technique. Using a diffraction-based forward simulation and inversion method, we examine the limitations due to noise, amplitude drift, atmospheric turbulence, and horizontal inhomogeneity.
