Incoherent dedispersion
WebA fully real-time coherent dedispersion system has been developed for the pulsar back-end at the Giant Metrewave Radio Telescope (GMRT). 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 … WebThe dedispersion step is typically compiled as part of a larger pipeline, but this repo contains two example programs in the bin/ directory to test and autotune a dedispersion kernel. …

WebAbstract. Incoherent dedispersion is a computationally intensive problem that appears frequently in pulsar and transient astronomy. For current and future transient pipelines, … WebJun 10, 2015 · Coherent dedispersion ([11]) can provide significant improvements over incoher- ent dedispersion by completely removing the effects of interstellar dispersion, and recovering the original Nyquist time resolution of the sampled voltage signal.
WebApr 25, 2024 · Shifan Zuo, Xuelei Chen. We 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 time-frequency data to a straight line in the parameter space, and points on the same ...
