WebThe dedispersion pipeline uses the single phased array voltage beam produced by the existing GMRT software back-end (GSB) to produce coherently dedispersed intensity … WebWe describe our software pipeline, which accepts short integration ( ms) spectrometer data from each antenna in real time during correlation and performs an incoherent dedispersion separately for each antenna, over a range of trial dispersion measures. The dedispersed data are processed by a sophisticated detector and candidate events are recorded.

WebJan 1, 2024 · Coherent dedispersion is a convolution of the raw signal voltages (Nyquist sampled time-series) with the inverse of the transfer function of the interstellar medium (ISM). The convolution is most efficiently performed as a multiplication in the frequency domain through the discrete convolution theorem (see Press et al., 1992 Chapter 13.1). WebAbstract.
