WebJan 1, 2016 · Rayleigh treated the scattering of light by a spherical particle, whose diameter is much smaller than that of the wavelength of light. It is generally accepted that this size regime applies for particles (or molecules) of size less than 1/10th the vacuum wavelength, λ, of the incident light.Rayleigh considered a plane wave incident on a dielectric sphere of … WebThe fluctuation loss of a steady target is with the typical value of 1 to 2 Decibels relatively small at a probability of detection PD=60%. The cases I and III apply for search radars. The fluctuation loss depends on the probability of detection and is shown in Figure 4. There is a fluctuation gain for a PD<30% . campervans north east uk
