Effect Evaluation for Jamming on SAR Based on Two Dimension Symmetry Cross Entropy
Due to the lack of consideration of position information , the existing SAR jamming effect evaluation methods based on symmetry cross entropy have the deficiency of evaluation veracity. Aimed at indeterminacy and complexity of jamming effect on SAR image, combined the existing theory of symmetry cross entropy, brought forward an improved SAR jamming effect evaluation method based on two dimension symmetry cross entropy, made gray-scale information and position information one dimension character of SAR image respectively, gray-scale value was the token of pixel gray-scale information, while the average of pixels gray-scale value around was the token of position information. Experimented using real SAR echo data , and compared the results using discriminability which proves the validity and superiority of SAR jamming effect evaluation method based on two dimension symmetry cross entropy.
