A Synthetic Aperture Radar ( S A R ) simulator of an extended three-dimensional scene is presented. It is based on a facet model for the scene, asymptotic evaluation of SAR unit response, and two-dimensional fast Fourier transform (FFT) code for data processing. Prescribed statistics of the model account for a realistic speckle of the image. The simulator(More)
The Cassini Titan Radar Mapper imaged about 1% of Titan's surface at a resolution of approximately 0.5 kilometer, and larger areas of the globe in lower resolution modes. The images reveal a complex surface, with areas of low relief and a variety of geologic features suggestive of dome-like volcanic constructs, flows, and sinuous channels. The surface(More)
Synthetic aperture radar (SAR) raw signal simulation is a powerful tool for design of oil slick detection and interpretation systems. In this paper, the ocean simulation issues are presented, and the main problems relating to the oil presence on the sea surface are treated. Attention is focused on the electromagnetic side of the problem, with care to the(More)
AbstructIn this paper, we exploit the interferometric multifrequency potentiality of the SIR-CK-SAR system which is equipped with an L-, C-, and X-band sensor. We present a solution to improve the unwrapping performance of the Cand X-band data by considering the L-band unwrapped pattern. A new algorithm for the generation of a single digital elevation model(More)
