Title:
GENERALIZED SIMILARITY MEASUREMENT METHOD AND APPARATUS FOR POLARIMETRIC RADAR, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/116455
Kind Code:
A1
Abstract:
Disclosed in the present invention are a generalized similarity measurement method and apparatus for a polarimetric radar, a device, and a storage medium. The method comprises: respectively obtaining polarized target coherence matrixes of two objects to be measured; decomposing the two polarized target coherence matrixes according to a preset decomposition rule to obtain a first decomposition component of the first polarized target coherence matrix and a second decomposition component of the second polarized target coherence matrix; performing permutation without repetition on the first decomposition component and the second decomposition component, and calculating the polarized similarity of each permutation to obtain a plurality of polarized similarity values; and selecting a minimum polarized similarity value as a generalized polarized similarity measurement result of said two objects. According to the method in the present invention, the similarity of different types of objects can be measured, the universality of the method is improved, and the method is higher in applicability in polarized SAR data processing and application.
