Incoherent target
Webcan be either spatially coherent or incoherent. The reason is that the spatial coherence of OSH depends on the recording geometry. If the active area of the detector is large enough, the hologram is formed by the superposition of the irradiance response of the object target, resulting in an incoherent hologram. WebFeb 9, 2016 · Target decomposition theorems were formalized to express the average of the scattering mechanism in a resolution cell. The scattering processes in the crops and other surface features can be analyzed in both coherent and incoherent methods.

WebFeb 9, 2016 · Incoherent target decompositions (ITD) are appropriate for distributed targets and cases where coherence between elements is not assumed. Model-based ITDs have been developed to decompose the backscattered power into its constituent elements [ … WebDec 5, 2024 · The other is the case when a received signal is composed of only incoherent components. Incoherent components in actual ultrasound imaging, for example, speckle echoes and out-of-focus echoes, are partially coherent, but a perfectly incoherent component, that is, random noise, is considered in this theoretical consideration as an …
