Thanks to the signal processing applied to radar signal, radar systems can provide images with a very high resolution. With regard to these properties, one can estimate that radar images are used to get elevation terrain considering the basic characteristics of a radar image. This paper examines one way to produce DEM (Digital Elevation Models) from a mountainous area (the French Alps). So, we organize...
We present a high resolution method for spotlight mode SAR imaging that utilizes pole/residue modeling of projected target reflectivity density function and tomographic reconstruction. Utilization of a matrix pencil method (MPM) allows super resolution to be achieved in range for a single imaging angle. Hence the quality of the image reconstructed is also improved. It is shown that the method is very...
