The First Moments of the Variance- and Cross-spectra of Standard and Interferometric Clean-air-Doppler-radar Signals

It is a translated, revised and slightly extended version of the author's habilitation thesis "Die ersten Momente der Varianz- und Kreuzspektren der Signale von konventionellen und interferometrischen Clear-air-Doppler-Radars" (in german), which had been also accomplished during the stay at NCAR.

This work was motivated by NCAR's and the author's interest to understand in some more detail effects of inhomogeneity and anisotropy of refractive-index irregularities on the signals measured with NCAR's MAPR radar system and other standard and interferometric atmospheric Doppler radars.
