Incoherent dedispersion
WebApr 13, 2024 · To generate a noisy SUT, the signal of interest was combined with an amplified and filtered incoherent noise source obtained from a superluminescent diode, with its power spectral density being confined to a narrow 3-dB bandwidth (< 200 GHz). In order to prevent any polarization-dependent filtering from mitigating noise effects, a … WebDedispersion¶ New in version 0.5.

WebIncoherent radio emission will produce an image-domain, slow radio transient (Hallinan et al. 2024). Apertif allows for the study of both kinds of emission. Afterglow searches are carried out in image domain ... Dedispersion. This module is the base for the searching algorithm. It implements dedispersion using an algorithm derived from the ... WebTo overcome the dispersion effect, incoherent dedispersion methods are often applied. The tranditional inchoherent dedispersion methods are computationally expensive and troublesome. To deal with ...
WebThe backend to the 990 MHz receiver also has incoherent dedispersion across 8 adjacent channels allowing a study of individual pulses. A new addition is the daily monitoring of 10 other young, active pulsars with the 26-metre radio telescope. A cryogenic dual polarisation 20 cm receiver with system temperature of 60 K centred at 1522 MHz is fed ... WebSep 4, 2015 · Coherent dedispersion necessarily requires one to process the original Nyquist sampled voltage signal from the phased array beam. Since this voltage data cannot be integrated, it either has to be stored on a disk for offline processing, or …
WebWe consider the Hough transformation algorithm for incoherent dedispersion and pulse search. Our input data is a time stream of spectrum which is the short time integral of the intensity, either from a single receiver or from the synthesized beam of an array. 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 …
