Abstract: PURPOSE: A device for processing a synthetic aperture radar image by using root conversion and a method thereof are provided to implement a calculation process in real time by defining an energy function using m-th root conversion and by removing noise from input images with the defined energy function. CONSTITUTION: An image acquisition unit (110) acquires an input image on an object area. An image processing unit (120) generates an output image in which noise is removed by removing the noise with an energy function using a previously defined m-th root conversion from the acquired input image. An image display unit (130) displays the output image. An image storage unit (140) stores the acquired input image and the output image.
