Abstract :
A novel method of 3-D geometric feature extraction of vehicle target based on the fusion of the shadow information from a very few (just 3 to 5) 2-D high resolution SAR imagery with different azimuth is proposed in this paper. And the validity of the proposed method has been proven by a large number of experimental results using MSTAR measured SAR imagery.
