The Geophysics Directorate of the U.S. Air Force developed a unique 11-cm (S-band) coherent polarimetric radar. The radar can transmit signals of alternating orthogonal polarizations, with either circular or linear basis, and receive signals of polar

Polarization is a fundamental descriptor of electromagnetic waves and, as such, has received the attention of scientists for over three centuries, beginning with the discovery of double refraction in crystals by Bartolinus and the discovery of polari

From the earliest years of meteorological radar research, the potential utility of polarization techniques was recognized by several research organizations. Their experimental and analytical endeavors are described by Seliga et al. (Chapter 14). The

A numerical model was developed to simulate the power spectra, cross-spectrum, and derived functions obtainable from a coherent polarization-diversity radar. The model was used to investigate the effects of air velocity variance, radar system noise,

A theory is presented for interpretation of the autocovariances and cross-covariance derivable from coherent polarization diversity radars. At zero lag time these quantities yield the “main” received power, the depolarization ratio, the cross-cor

Differential propagation effects are a key element in the design and use of dual-channel radars for meteorological measurements. Particularly in the case of circularly polarized signals, these effects determine the maximum ranges to which certain mea
