“…Ground track differences as great as 90 degrees, albeit at 30 degrees grazing angle, have been demonstrated to achieve good coherence for 'bumpy' topographies. 7 Anecdotal evidence also suggests that matching squint angles is a greater problem for flight paths that are circles, especially under manual control of a pilot.…”

Coherent Change Detection (CCD) with Synthetic Aperture Radar (SAR) images is a technique whereby very subtle temporal changes can be discerned in a target scene. However, optimal performance requires carefully matching data collection geometries and adjusting the processing to compensate for imprecision in the collection geometries. Tolerances in the precision of the data collection are discussed, and anecdotal advice is presented for optimum CCD performance. Processing considerations are also discussed.-4 - ACKNOWLEDGEMENTS

“…Moreover, problems due to radar shadowing particularly in urban areas, render this approach sub-optimal. The crossing-track collection geometry and subsequent coherent SAR stereo processing proposed and demonstrated in [9], is potentially the most powerful technique for the extraction of DEMs over urban areas. Data is collected such that the centres of both synthetic apertures coincide.…”

In this paper we discuss various methods for collecting and exploiting SAR imagery of urban areas. In particular we describe techniques that utilise both intensity and phase information to provide information beyond that of the standard image product. We demonstrate techniques to produce digital elevation maps and SAR movies, using airborne radar data. Examples showing the applications and limitations of these approaches to the task of urban surveillance are presented.

It is a difficult problem for airborne synthetic aperture radar (SAR) to obtain the target 3D coordinate information when the highly precise elevation information is unknown. Stereo SAR detects the same area with multiple angles, so that the height of the target can be obtained by using the multi-angle imaging projection results. On the basis mentioned above, a back projection (BP) imaging model based target height inversion and coordinate correction method is studied in this paper. Mechanism of imaging error and realization of height inversion algorithm are analyzed in detail under horizontal and subduction motions, so the proposed method is flexible for application in a variety of motion states. Simulation experiments illustrate the effectiveness of the proposed method.
