Paper Abstract

This paper presents algorithms designed to exploit multi- pass SAR imagery from the Tactical Endurance SAR sensor used on the Predator MAE-UAV. The multi-pass exploitation begins by using several images from the data set to build a detailed site model. The site modeling step is based on a multiresolution segmentation algorithm for the individual images, followed by height estimation, registration, and merging the individually labeled images into a common ground plane site model. After constructing the site model, target detection is performed on additional images of the site. The site model is then used to eliminate false alarms and detect changes in vehicle locations. After explaining the operation of our current exploitation system, we briefly address the improvements offered by segmenting SAR data formed using modern spectral estimation.
