Image Texture Extraction Using Multi-Resolution Scale Wavelets

Texture feature extraction from images using multi-resolution scale wavelets (two key parameters: R1 ranging 1.1-1.2 for scale adjustment, R2 as threshold between 10-30)

Calculating Divergence

Input: psi grazing angle (can be vector or scalar) in degrees; r1 ground distance between radar and specular point (km); r2 ground distance between specular point and target (km); ht target height (m); hr radar height (m). Output: D divergence factor.
