[0050] The present invention will be further described below in conjunction with the drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.
[0051] Reference figure 1 , The implementation steps of the present invention are as follows:
[0052] Step 1) Input two SAR remote sensing images of the same area and different time phases, which are respectively marked as: I 1 And I 2 .
[0053] Step 2) Use ENVI remote sensing software to 1 And I 2 To perform geometric correction, the specific steps are as follows:
[0054] 21) Display the reference image and the image to be corrected.
[0055] 22) Start the geometric correction module.
[0056] 23) Collect ground control points GCPs.
[0057] 24) Select the calibration parameter to output the result.
[0058] 25) Check the calibration results.
[0059] Step 3) I after geometric correction 1 And I 2 , U...
