[0021] refer to figure 1 . According to a SAR image synthesis method for enhancing target features proposed by the present invention, firstly, the registered synthetic aperture radar SAR image and optical digital image obtained from the outside scene are read into the computer memory image synthesis program software, and the color conversion in the computer is performed. The module performs color preprocessing on the optical image, divides the red R, green G, and blue B into three-component color image pixels, and converts the color image into a grayscale image through brightness calculation; the SAR image target extraction module extracts the target area information, and converts the SAR The normalized histogram of the image is used as a statistical distribution model to divide the SAR image into the target area and the background area, and then detect the bright spots in the SAR image through the constant false alarm target, and according to the prior target label informatio...
