polarimetric synthetic aperture radar (pol.-sar) allows us to implement the recognition and classification of radar targets. this article investigates the arrangement of scatterers by sar data and proposes a new look-up table of region (ltr). this look-up table is based on the combination of (entropy h/anisotropy a) and (anisotropy a/scattering mechanism α), which has not been reported up now. ...

Processing oversampled signals in range with a whitening transformation has been proposed as a means to reduce the variance of meteorological variable estimates on polarimetric Doppler weather radars. However, the original formulation to construct decorrelation transformations does not account for mismatches in the polarimetric channels, which results in abnormally biased polarimetric variable ...

Dual polarization radars have shown considerable improvement of quantitative estimation of rainfall rate and raindrop size distribution (DSD) parameters. Most studies have been done with S and C-band radars and only a few studies with higher X-band weather radars. X-band radars have the advantages of lower cost and higher differential phase shift but with higher attenuation too. Furthermore, th...

The present doctoral thesis deals with radar polarimetry, namely with the investigation of properties of polarimetric variables potentially useful in radar meteorology. For use with dual-polarization radars, the degree of polarization is analyzed. This variable is available to planned operational radars. The degree of polarization is dependent on transmit polarization state and, consequently, i...

This study presents a first analysis of precipitation and related microphysical processes observed by three polarimetric X-band Doppler radars (BoXPol, JuXPol and KiXPol) in conjunction with a ground-based network of disdrometers, rain gauges and vertically pointing micro rain radars (MRRs) during the High Definition Clouds and Precipitation for advancing Climate Prediction (HD(CP)2) Observatio...

With the advent of high-frequency radio frequency (RF) circuits and components technology, millimeter-wave (MMW) radars are being proposed for a large number of military and civilian applications. Accurate and high-resolution characterization of the polarimetric radar backscatter responses of both clutter and man-made targets at MMW frequencies is essential for the development of radar systems ...

The manuscript presents an interesting and important study of retrieval cloud particles’ characteristics from differential reflectivity (ZDR) and the correlation coefficient (CC) measured with polarimetric radar operating at a frequency of 35 GHz. Two measured radar variables allow retrieving the dielectric axis ratio and degree of orientation of cloud ice particles. The paper is a substantial ...

1. It is an interesting study of retrieval cloud particles’ characteristics from differential reflectivity (ZDR) and the correlation coefficient (CC) measured with polarimetric radar operating at a frequency of 35 GHz. Two measured radar variables allow retrieving the axis ratio and degree of orientation of cloud ice particles. The approach can be used for polarimetric scanning radars at other ...

Polarimetric Doppler radars provide valuable information about the kinematic and microphysical structure of storms. However, in-depth analysis using radar products, such as Doppler-derived wind vectors and hydrometeor identification, has been difficult to achieve in (near) real time, mainly because of the large volumes of data generated by these radars, lack of quick access to these data, and t...
