WebJan 31, 2024 · A fully real-time coherent dedispersion system based on GPUs has also been developed for the pulsar backend at the Giant Metrewave Radio Telescope (GMRT) … 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 ...

Real‐time, fast radio transient searches with GPU de‐dispersion

WebJan 18, 2024 · [docs] class DedisperseSamples(DisperseSamples): """Incoherently shift a time stream to correct for a dispersive time delay. This task does not handle any in-channel dispersive smearing, but only shifts the samples according to the mid-channel frequency. WebWe present and implement the concept of the Fourier-domain dedispersion (FDD) algorithm, a brute-force incoherent dedispersion algorithm. This algorithm corrects the frequency … cost breast augmentation
