Polarimetric Calibration of the Ku-Band Advanced Polarimetric Radar Interferometer [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2018
Differential interferometry using ground-based radar systems permits to monitor displacements in natural terrain with high flexibility in location, time of acquisition, and revisit time. In combination with polarimetric imaging, discrimination of different scattering mechanisms present in a resolution cell can be obtained simultaneously with the ...

Observations of Insects and Birds With a Polarimetric Radar

IEEE Transactions on Geoscience and Remote Sensing, 1998
The authors present observations of biological scatterers with a polarimetric weather radar. The radar has a pencil beam, a high power, and a wavelength of 10 cm. It transmits horizontally and vertically polarized waves alternately. The available polarimetric variables are differential reflectivity, differential phase, and correlation coefficient ...

Polarimetric FMCW weather radar

2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015
This study which was conducted as a Master's thesis, is a radar system working at X band. In this system, a 2 Watt continuous electromagnetic wave which is modulated with frequency ramp of 30 MHz bandwidth is generated and radiated through TX antenna. The scattered signal from the hydrometeors is multiplied with the transmitted one and beat signal is ...

Polarimetric Radar for Accurate Navigation

Canadian Journal of Electrical and Computer Engineering, 1987
A novel and commercially viable solution to the problem of blind navigation of a ship along a confined waterway is described. The solution is based on the use of radar polarimetry. At the heart of the system is a patented passive (nonpowered) retrodirective reflector that is capable of rotating the incident polarization through 90°.
