Abstract :
The land cover change detection method using the standard deviation of the backscattering coefficient was suggested. Comparing with the previous method using spatial information such as correlation coefficients, it reduced the commission errors in the agricultural areas. It was found that the detection accuracy increased when the target area was large, but each changed target was difficult to detect for crowded and complex urban areas, even though high-spatial resolution airborne SAR data was used.
