The incoherent wave is modeled by the random uctuations of the acoustic pressure, which dominate the expectation at long ranges from the source. We use the existing theory of wave propagation in random waveguides to analyze the inverse problem of estimating the source from incoherent wave recordings at remote arrays.

WebCoherence In wave optics, we make a distinction between coherent and incoherent sources of light. Any real source of light is not exactly monochromatic (single color), but has a range or band of frequencies, Δ f. An incoherent source of light lacks a specific direction and has a relatively large Δ f. By contrast, a coherent source has a specific direction with a much … green mint mouthwashWe describe theoretically the phenomenon of large-scale incoherent shock within the general framework of the wave turbulence formalism.
