The penetrability of electromagnetic radiation is limited

generally the penetrability depth of the microwave is less than 5m

which is called ’skin depth’. However it is very important for us to know the depth of structure in remote sensing images. Generally it can be acquired by overlying the continuous contour of gravity and magnetic data on to remotely sensed images or integrating remotely sensed and gravitational and magnetic data. But this is qualitative and indirect method. A new method

Euler Deconvolution is introduced in the paper. The structure location

stretch and depth could be estimated by using Euler Deconvolution of geophysical data. And the depth of structure in remotely sensed images could be displayed by overlying the Euler Deconvolution results on to the remotely sensed images. The method was applied in the western slope of SongLiao Basin

which is quantitative and more efficient than other geophysical methods. And the depth of structure in remotely sensed images cannot be estimated except geophysical methods.
