Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings.
[0032] refer to figure 1 , and describe in detail the specific steps for realizing the present invention.
[0033]Step 1, generate a training set.
[0034] The sample set is composed of samples containing M types of ground stationary targets, each of which contains at least 200 synthetic aperture radar SAR complex images, where M≥3.
[0035] Take the modulus of each SAR complex image in the SAR complex image sample set to obtain the SAR real image sample set including amplitude information.
[0036] Using the component analysis method, the component binary image corresponding to each complex image in the SAR complex image sample set is obtained, and all the component binary images are constructed into a component binary image sample set containing electromagnetic scattering information.
[0037] The component analysis method is as follows:
[0038] In the first ste...
