[0053] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples of implementation. It should be understood that the specific implementation examples described here are only used to explain the present invention, and are not intended to limit the present invention.
[0054] For the acquired fully polarimetric SAR image, the polarization scattering matrix (S matrix) is used to express the image data of four channels, as shown in the following formula. In this formula, S pq Indicates the backscattering of the target when q polarization is transmitted and p polarization is received, p and q are horizontal h or vertical v polarization. Generally speaking, for a reciprocal medium, according to the single-station reciprocity principle, the S matrix will satisfy the S hv = S vh condition, the scattering matrix is a s...
