Embodiment Construction
[0034] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0035] Such as figure 1 Shown: the present invention is the technical process of automatic determination of the optimal resolution of synthetic aperture radar wind field inversion, and the specific calculation method includes the following steps:
[0036] Step 1. Acquiring SAR images containing both co-polarization and cross-polarization, and preprocessing the acquired images;
[0037] Specifically, to obtain SAR images that include co-polarization and cross-polarization at the same time, at present, many synthetic aperture radars carried by satellites have multi-polarization imaging methods, such as the recently launched Sentinel of the European Space Agency, which can provide a large number of VV+VH Polarized or HH+HV polarized images, where H is the horizontal wave and V is the vertical wave, VV and HH are co-polarized, and VH and HV are cross-polarized.
