What is the Rayleigh Distribution & How does it work?

The Rayleigh distribution describes the magnitude of a two‑dimensional vector whose components are independent, zero‑mean Gaussian variables with equal variance. It is widely used in signal processing, reliability engineering, and oceanography to model random amplitudes.

Its probability density function (PDF) is given by a simple closed‑form expression that depends on a single scale parameter (sigma). The distribution is defined for non‑negative values of the random variable (x) and integrates to one over the interval ([0,infty)).

Key statistical measures such as the mean, variance, and cumulative distribution function (CDF) can be derived analytically, making the Rayleigh distribution a convenient choice for theoretical analysis and practical computation.
