Abstract
The conventional result for the signal‐to‐noise ratio in an optical heterodyne detector is shown to apply to the mixing of a stable local oscillator with any radiation field which gives rise to a stationary narrow‐band i.f. signal. The result is explicitly demonstrated for radiation scattered from a diffuse target, which may be represented as a narrow‐band Gaussian random process.This publication has 4 references indexed in Scilit:
