Interferometric Synthetic Aperture Radar
This paper provides a brief review of interferometric synthetic aperture radar (InSAR), its history, the theory, and design / implementation / processing issues. Along-track, single-pass and repeat-pass cross-track interferometry are reviewed. Specific topics addressed include error sources and phase-unwrapping techniques. Several examples of InSAR applications are presented. Introduction For y...
متن کاملInterferometric synthetic-aperture radar (InSAR)
Geodesists are, for the most part, a patient and hardworking lot. A day spent hiking to a distant peak, hours spent waiting for clouds to clear a lineof-sight between observation points, weeks spent moving methodically along a level line – such is the normal pulse of the geodetic profession. The fruits of such labors are all the more precious because they are so scarce. A good day spent with an...
متن کاملCoherent interferometric imaging for synthetic aperture radar
This paper shows that the coherent interferometric imaging strategy originally proposed in the context of passive or active arrays of antennas can be implemented for synthetic aperture radar, in which a single antenna is used as an emitter and as a receiver at successive positions along a trajectory. The idea is to backpropagate the cross correlations of the recorded signals over selected frequ...
متن کاملAdvances in Bistatic Inverse Synthetic Aperture Radar (Invited Session on Advances in Inverse Synthetic Aperture Radar)
Bistatic geometries are enabled in scenarios where multiple separated transmitters and receivers are employed as well as when illuminators of opportunity are exploited. Bistatic Inverse Synthetic Aperture Radar (B-ISAR) becomes the radar imaging tool for obtaining non-cooperative target images in arbitrary bistatic configurations. Theoretical aspects and real data experiments have been conducte...
متن کاملForest mapping and monitoring with interferometric Synthetic Aperture Radar (InSAR)
8 9 10 A Synthetic Aperture Radar (SAR) is an active sensor transmitting pulses of polarized 11 electromagnetic waves and receiving the backscattered radiation. SAR sensors at different 12 wavelengths and with different polarimetric capabilities are being used in remote sensing of 13 the Earth. The value of an analysis of backscattered energy alone is limited due to ambiguities 14 in the possib...
