WebIf so, the optimal detector performs phase coherent summation of received signals which can result in very high target location accuracy. [10] If not, the optimal detector performs incoherent summation of received signals which gives diversity gain. WebSep 16, 2024 · An object is often illuminated by a spatially incoherent light source and then imaged. The field reflected or transmitted by the object is then partially coherent. We have shown in Chapter 5 that the degree of mutual coherence in the object increases when the distance between the source and the object is increased.

WebMay 14, 2015 · Two comments were made by Inal and Benmouna about this work with regard to (i) the incoherent summation of the individual hyperfine components of the 1 s 2 p 3 / 2 1 P 1 → 1 s 2 1 S 0 transition and (ii) the treatment of the hyperfine-induced E 1 − M 2 multipole mixing in the 1 s 2 p 3 / 2 3 P 2 → 1 s 2, 1 S 0 fine-structure component. WebDec 23, 2024 · However the emission of fluorescence is always given within a finite spectrum. When the imaging system’s point spread function is measured, this can be described as an incoherent summation of individual single-wavelength PSF’s, weighted by the emission spectrum.

WebIncoherent scatter radar theory is the most well recognized applied technique for studying the Earth's ionosphere, which was first proposed by Professor William E. Gordon in 1958. In this sense, a radar beam scattering off electrons in the ionospheric plasma produces an incoherent backscatter.
