Abstract:

In order to give full play to the SAR(Synthetic Aperture Radar) on the deep geological target precise detection and rapid analytical advantage, to further improve the resolution of ground target recognition, based on discussing the basic principle and data analysis method, polarization measuring, interferometry and differential interferometry for SAR technology are analyzed. The favorable and unfavorable conditions of ultra wideband SAR applications are summarized. The scope of application of this technology and the technical specification, provides a theoretical basis and technical guidance for the SAR in the digital geological science and applied in geoinformation science.

Key words: synthetic aperture radar(SAR), polarization measuring, interferometry, differential interferometry, ultra-bandwidth SAR
