Paper Abstract

We consider a monostatic synthetic aperture radar system traversing an arbitrary trajectory on a non-flat topography. We present a novel edge detection method applicable directly to SAR received signal. Our method first filters the received data, and then backprojects. The filter is designed to detect the edges of the scene in different directions at each pixel reconstructed. The method is computationally efficient and may be implemented with the computational complexity of the fast-backprojection algorithms. We present numerical experiments to demonstrate the performance of our method.
