WebNov 30, 2002 · Pre-detection, or ``coherent,'' dedispersion is a powerful technique which completely eliminates the effects of dispersive smearing on pulsar profiles, greatly … WebFeb 23, 2024 · By using a single subband, we avoid artefacts due to the inaccuracy of incoherent dedispersion. There are clear few-bin-wide temporal structures in the 31.25 ns profile of burst B3 (Fig. 1 ).
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 … WebFeb 27, 2013 · Coherent dedispersion. Since the baseline-based incoherent dedispersion performed before folding the visibility time-series at the best-fit topocentric model is not adequate for the study of MSPs at lower frequencies, we implement an antenna-based coherent dedispersion.
