Detection of Single and Double PSs Based on Scattering Characteristic in SAR Tomography

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 463)

Abstract

Synthetic aperture Radar (SAR) tomography has been widely used in 3D reconstruction in urban area. Nevertheless, how to exactly detect persistent scatterers contained in one range-azimuth resolution pixel still requires further researching. In this paper, a new detection method based on scatterer’s characteristics is proposed. The model is built under the hypothesis test theory and determines threshold according to probability of detection and false alarm. In the experiment with SAR images acquired by TerraSAR-X, this method has exhibited good performances in detecting single and double persistent scatterers.
