Distorted structures in half-filled p-band materials
Journal of Physics: Condensed Matter, 2019Abstract Many half-filled p-band materials form complex, semiconducting or semi-metallic crystallographic structures, which are commonly conceived of as distortions of simpler, higher-symmetry structures. This distortion is conventionally attributed to the energy gained by the opening of a band gap in the vicinity of the Fermi level ...

P band penetration in tropical and boreal forests: Tomographical results
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011In this paper we discuss some relevant features observed concerning wave penetration at P-band in boreal and tropical forests. The discussion will be based on results obtained from the multi-polarimetric and multi-baseline data-sets relative to the forest sites within the Krycklan river catchment, Sweden, and the area of Paracou in French Guyana ...

Research of P band circular polarization SAR
2016 CIE International Conference on Radar (RADAR), 2016For space-borne P band Synthetic Aperture Radar (SAR) application, an airborne experimental circular&linear polarimetric SAR system is developed, this paper presents the instrument and airborne test result. Compared to linear polarization of P band, circular polarimetric SAR shows remarkable penetration efficacy in tropical jungle foliage covered ...

The P-band SAR Satellite: Opportunities and Challenges
2019 6th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR), 2019The P-band frequency is less common in spaceborne synthetic aperture radar (SAR) systems, while has superior abilities on penetration through the vegetation canopy and soil compared with X-, C- and L-bands. As observations from P-band SAR satellite will offer an unique opportunity to estimate forest biomass, map the topography of forest floors and ...

Simulations of ionospheric effects on SAR at P-band
IEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 2003There has been an increasing interest in the use of space-borne SAR for measuring forest biomass which requires the use of longer wavelengths for enhanced foliage penetration. However, the propagation characteristics of the wave will be seriously affected by the ionosphere, especially below P-band (500 MHz).
