چکیده

This contribution is a tutorial introduction to the phenomenological theory of radar polarimetry for the coherent scatter case emphasizing monostatic backscattering and forward scattering (transmission). Characteristic similarities and differences between radar polarimetry and optical polarimetry and the role of linear and antilinear operators (time-reversal) are pointed out and typical polarimetric invariants are identified.

Polarimetry for Weather Surveillance Radars

Scientific evidence accumulated over the last decade indicates that weather radar polarimetry has passed two important tests. First, as suggested by theory, polarimetric signals contain significant information about hydrometeor habits; and second, the information can be retrieved with sufficient accuracy to be useful. If it passes the cost effectiveness test, the technique should be adopted for...

Fundamental Study on NDT of Building Wall Structure by Radar

GB-SAR (Ground Based Synthetic Aperture Radar) for inspection of wooden and concrete walls and structures has been developed and the system was evaluated by test measurements. The GB-SAR system uses frequency bandwidth 1-10GHz, and it can acquire full polarimetric radar signal. Then Synthetic Aperture (SAR) Radar signal processing is used to reconstruct 3-dimenatioal images of inner structure o...

A Fully Polarimetric Borehole Radar Based Numerical Modeling: Fully Polarimetric Response to Synthetic Natural Fractures and “fluid Substitution”

A fully polarimetric borehole radar system with four combinations of dipole and cylindrical slot antennas, as shown in Fig. 1, was developed to acquire fully polarimetric data sets in drilled boreholes [1]. The system in conjunction with a methodology of radar polarimetry analysis, proposed in previous (a) Measurement configuration (b) Antenna arrangements for polarimetric data collection Fig. ...

Compact Polarimetry at the Moon: The Mini-RF Radars

The Mini-RF radar aboard India’s lunar Chandrayaan-1 satellite [1] (2008-9) was the first polarimetric synthetic aperture radar (SAR) outside of Earth orbit. The architecture of that radar—and of its more advanced two-frequency sibling on NASA’s Lunar Reconnaissance Orbiter [2] (2009)—is hybrid dual-polarimetric [3][4]. This architecture is a form of compact polarimetry [5] in which the dual-re...
