A method for calculating mountainous area adjacent surface reflected radiation

The invention belongs to the technical field of remote sensing, and particularly discloses a method for calculating mountainous area near-surface reflected radiation. The method comprises the steps ofsetting a distance range of near-surface reflection, and determining the size of a filtering window by combining remote sensing image spatial resolution; calculating a distance value, an angle valueand a weight value between each filtering window pixel and the central point in a polar coordinate mode by taking the central point of the filtering window as an original point; performing comparativejudgment and analysis according to the angle value and the distance value of the filtering window pixel and the elevation value and the slope value corresponding to the remote sensing image pixel, and determining a remote sensing image pixel generating adjacent reflection radiation at the center of the filtering window; based on the determined adjacent reflection radiation image pixels, carryingout surface adjacent reflect
