Abstract: Several models have been developed in the past to describe the distribution of hydrometeor canting angles and the resulting effects on polarimetric radar measurements. These models are reviewed to compare their characteristics ...

Abstract: 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 ...

Abstract: Previous observations of clear air echo layers by high-resolution radar are reviewed briefly and compared with theoretical models. Quantitative radar reflectivity records reveal a variety of features common to these echo ...

Abstract: An instrumented aircraft and a vertically-pointing FM-CW radar were used to investigate waves and turbulence within a very strong low-level temperature inversion. Temperature and wind velocity data from the aircraft were ...

Abstract: Changing orientations of hydrometeors due to rapidly changing electric fields in thunderstorms were observed by the 11-cm polarimetric Doppler radar that was operated by the Geophysics Directorate of Phillips Laboratory ...

Abstract: The measurement capability of a polarization diversity radar is limited by several characteristics of the system and particularly by the performance of the antenna, which is characterized by the integrated cancellation ...

Abstract: 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, ...
