Abstract
The leading contour method is the most important feature for the vehicle target aspect estimation in the synthetic aperture radar image. Making full use of the leading contour, the method for vehicle target aspect estimation can be more accurate and efficient. This paper analyzes how to use the leading contour in the aspect estimation, and presents a new way to estimate the aspect fast, which is associated with the Radon transformation which is introduced to eliminate the ambiguity of the aspect estimation at a horizontal or vertical angle. The simulation experiment is made using MSTAR pubic target database, and the results show that the method can get accurate targets aspect estimate region.关键词
