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 … WebJan 18, 2024 · Parameters ---------- ih : task or `baseband` stream reader Input data stream, with time as the first axis. dm : float or `~baseband_tasks.dm.DispersionMeasure` quantity Dispersion measure.

WebIncoherent dedispersion is a computationally intensive problem that appears frequently in pulsar and transient astronomy. For current and future transient pipelines, dedispersion … 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.
WebIn incoherent dedispersion mode, multiple samplers can be used to cover up to 6 GHz (depends on receiver and IF system limits) –Data still written to sub-directories by bank … 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).
WebSep 1, 2015 · The dedispersion pipeline uses the single phased array voltage beam produced by the existing GMRT software back-end (GSB) to produce coherently dedispersed intensity output in real time, for the currently operational bandwidths of 16 MHz and 32 MHz.
