A Unified Formalism of Incoherent, Quasi-coherent, and Coherent Correlation Siganls on Pulser-Pair Doppler Operation for a Cloud-Profiling Radar: Aiming for a space Mission

摘要

The correlation signals of the incoherent, quasi-coherent, and coherent backscatterings from clouds have been analytically calculated form a unified formalism based on the Eulerian description for a generic weather radar with pulse-pair function, especially aiming for a space-/airborne mission. The spectral broadening due to Doppler fading and wind shears is calculated from this formalism. Since the coupling of these two effects in the spectral broadening is subtantial, a conventional estimation is found not to be adapted for the space-/airborne radar.
