WebMay 21, 2008 · PROCEEDINGS VOLUME 6970. Algorithms for Synthetic Aperture Radar Imagery XV. Editor (s): Edmund G. Zelnio; Frederick D. Garber. For the purchase of this … Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam … See more SAR is capable of high-resolution remote sensing, independent of flight altitude, and independent of weather, as SAR can select frequencies to avoid weather-caused signal attenuation. SAR has day and night imaging capability … See more Synthetic-aperture radar determines the 3D reflectivity from measured SAR data. It is basically a spectrum estimation, because for a specific cell of an image, the complex-value SAR … See more SAR requires that echo captures be taken at multiple antenna positions. The more captures taken (at different antenna locations) the more reliable the target characterization. See more Polarimetry Radar waves have a polarization. Different materials reflect radar waves with different intensities, but anisotropic materials such as grass often reflect different polarizations with different intensities. Some … See more A synthetic-aperture radar is an imaging radar mounted on an instant moving platform. Electromagnetic waves are transmitted sequentially, the echoes are collected and the … See more SAR algorithms model the scene as a set of point targets that do not interact with each other (the Born approximation). While the details of various SAR algorithms differ, SAR processing in each case is the application of a matched filter to the raw data, for … See more Stripmap mode airborne SAR The antenna stays in a fixed position. It may be orthogonal to the flight path, or it may be squinted slightly forward or backward. When the antenna aperture travels along the flight path, a … See more
