Abstract
This paper proposes a new approach of combining multiple radar images from different frequencies to form a composite image. The method uses MatLab software to automatically combine GPR images. The basic image combination depends on the depth of radar wave penetration and frequency resolution. Therefore, each image is subdivided into horizontal slices along all image length (depending on the host material, number of images and number of frequencies used). Best slices (bands) are then combined into one image. Bands resulting from high frequencies appear at the top of the final image, and bands resulting from low frequencies appear at the bottom of the image, with medium frequency bands in between.
