WebAug 15, 2010 · The correlation function in the linear case (blue line) is modified by the interactions: the peak of the correlation function increases, and its width decreases. Web1.1 Correlation Interferometer Process A correlative interferometer is a process that determines the location of the emitter at an accuracy of 10 RMS, the technique measures the phase difference of the received signals obtained at two or more receivers’ array points. Consider two receivers separated properly by a distance d,
WebAlso called "post-detection correlation interferometer." It was invented by Robert Hanbury Brown , despite assurances from mathematicians and physicists alike that it was impossible. The signals are correlated after detection. Thus, no fringes are formed, and the signal is, using the multivariate theorem. WebPrinciple of Fast Spectral Correlation (FSC) Interferometry.
