WebJan 16, 2024 · The Rayleigh distribution is a continuous probability distribution.It owes its name to the English Lord Rayleigh (John William Strutt, 3rd Baron Rayleigh), who … WebAug 12, 2005 · The Rayleigh distance D = ka 2 /2, where k = 2πf/c, f is the frequency, c is the sound speed, and a is half the largest dimension, has been used to approximate the size of the geometric nearfield of plane radiators. We found that, for variously shaped radiators, the Rayleigh distance is useful in approximating the geometric nearfield size.
