Rayleigh scattering in radar
WebBy expanding the first-order small-slope approximation (SSA-1) scattering model in the polynomial terms containing convolutions of the sea wave spectrum, this letter quantitatively investigated how the convolutions of the sea wave spectrum affect the normalized backscattering cross section (NBCS) under various wind speeds, radar … WebBlue Sky. The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere. This scattering, called Rayleigh scattering, is more effective at short wavelengths (the blue end of the …
