Embodiment 1
[0091] The effect of the present invention can be further illustrated by the following experiments.
[0092] 1. Experimental data
[0093] The data used in the simulation experiment of the present invention are two sets of real polarimetric SAR images.
[0094]The first set of data comes from the L-band data of the Flevoland area in the Netherlands acquired by NASA / JPLARISAR. This is a four-view full-polarization data. We use a subimage of it with a size of 300×270 for experiments, such as figure 2 (a). There are six types of ground objects in this area, namely potatoes, sugar beets, bare land, barley, wheat, and peas. Marked with 6 colors respectively, such as figure 2 (b).
[0095] The second set of data comes from the L-band full-polarization data in the Foloum area of Denmark acquired by EMISAR. We use a subimage of it with a size of 943×1015 to do experiments, as image 3 (a). There are five types of land features in this area, namely rivers, forests (mainly con...
