Abstract
In practical applications of through wall radar imaging, the characteristics of the wall are usually unknown, which will defocus the image and displace the target from its true position. In this paper, a simple image autofocusing method is presented. This method employs only one search variable and a simplified focus measurement function, which can reduce the computation load of a real time radar system. The well-focused image in experiment validated the effectiveness of this method.
