摘要： The inclination direction monitor of the power transmission tower can issue an early-warning for the risk of the tower collapse, as well as the collapse direction. In this paper, we proposed a new method to retrieve the inclination direction of the power transmission tower using geocoding. First, the backscattering coefficient was utilized to separate the power transmission tower from the background, and figure up those coefficients along the tower direction to extract the main body of the tower. Second, the whole image was traversed by a 3*3 template window to refine and mark the most possible learning tower points. Finally, a distance-Doppler model was built to retrieve geographical coordinates of those marked points. According to the geographical coordinate of the tower point at different time, we got tower inclination direction. Compared with the actual measurement results of the study area, the retrieval result has a 0.0025° error, and the direction is north-east, consistent with the actual direction.
