Incoherent scatter - Wikipedia

In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function is linear, it can be used to estimate the causality between the input and output. http://www.sengpielaudio.com/AddingAmplitudesAndLevels.pdf WebThe source which emits a light wave with the same frequency, wavelength and phase or having a constant phase difference is known as a coherent source. A coherent source forms sustained interference patterns when the waves superimpose and the positions of maxima and minima are fixed.
