Circular Sites at Angkor: a Radar Scattering Model
نویسنده
چکیده
The paper describes the use of radar data to detect curvilinear patterns around circular mounds in the Angkor region. The radar data was acquired with equipment of the National Aeronautics and Space Administration and the Jet Propulsion Laboratory. A three-component scattering model is used to assess the presence of water at mound sites. The sensitivity of the radar allows detection of inundated areas covered by low-growing vegetation which are not apparent on optical imagery. The patterns are compared to comparable sites in Northeast Thailand, and used to suggest a similar prehistoric tradition of Khmer water management.

Radar interferometry offers new insights into threats to the Angkor site
The conservation of World Heritage is critical to the cultural and social sustainability of regions and nations. Risk monitoring and preventive diagnosis of threats to heritage sites in any given ecosystem are a complex and challenging task. Taking advantage of the performance of Earth Observation technologies, we measured the impacts of hitherto imperceptible and poorly understood factors of g...
متن کاملRadio-wave depolarization and scattering within ice sheets: a matrix-based model to link radar and ice-core measurements and its application
Crystal-orientation fabric (COF) has a large influence on ice-sheet flow. Earlier radar studies have shown that COF-based birefringence occurs within ice sheets. Radio-wave scattering in polar ice results from changing physical properties of permittivity and conductivity that arise from differing values of density, acidity and COF. We present an improved mathematical model that can handle all t...
متن کاملGOTCHA Experience Report: Three-Dimensional SAR Imaging with Complete Circular Apertures
We study circular synthetic aperture radar (CSAR) systems collecting radar backscatter measurements over a complete circular aperture of 360 degrees. This study is motivated by the GOTCHA CSAR data collection experiment conducted by the Air Force Research Laboratory (AFRL). Circular SAR provides wide-angle information about the anisotropic reflectivity of the scattering centers in the scene, an...
متن کاملMeteoroid head echo polarization features studied by numerical electromagnetics modeling
[1] Meteoroid head echoes are radar returns associated with scatter from the dense plasma surrounding meteoroids striking the Earth’s atmosphere. Such echoes are detected by high power, large aperture (HPLA) radars. Frequently such detections show large variations in signal strength that suggest constructive and destructive interference. Using the ARPA Long‐Range Tracking and Instrumentation Ra...
متن کاملClassification of Terrain by Implementing the Correlation Coefficient in the Circular Polarization Basis Using X-Band POLSAR Data
Classification of terrain is one of the most important applications of Polarimetric Synthetic Aperture Radar (POLSAR) image analysis. This paper presents a simple method to classify terrain by the use of the correlation coefficients in the circular polarization basis together with the total power of the scattering matrix in the X-band. The reflection symmetry condition that the co-polarized and...
