House structure feature enhancement using Multi-view high resolution SAR images

Electromagnetic scattering characteristics of house vary with different viewing directions. Due to the complex structure, such as facets, edges and corners, only parts of the house features are attainable under a certain observation angle in synthetic aperture radar (SAR) imagery. Since structure features are important for target detection and recognition, collecting more target features is great benefit for SAR application. In this paper, a new method of house structure feature enhancement using SAR images acquired in multi-view directions is proposed. By combining the images of targets of interest at different view angles, the aggregate radar scattering image is produced, which greatly facilitates structure interpreting. Results are presented with SAR images acquired by an airborne sensor, showing the promising performance of the method.
