Incoherent dedispersion
WebINIS Repository Search provides online access to one of the world's largest collections on the peaceful uses of nuclear science and technology. The International Nuclear Information System is operated by the IAEA in collaboration with over 150 members. WebWith coherent dedispersion, dedispersion is performed before squaring the orthogonal polarization signals to form the Stokes parameters. For signals that have already been squared to form the Stokes parameters, the “incoherent dedispersion” method is used. The time-series data of finite channels are shifted in time to

WebWe present a simple and fast method for incoherent dedispersion and fast radio burst (FRB) detection based on the Hough transform, which is widely used for feature extraction in image analysis. The Hough transform maps a point in the data maps to a straight line in the parameter space, and points on the same dispersed f−2 curve to a bundle of lines all … WebThe dedispersion pipeline uses the single phased array voltage beam produced by the existing GMRT software back-end (GSB) to produce coherently dedispersed intensity …
