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. WebTo overcome the dispersion effect, incoherent dedispersion methods are often applied. The tranditional inchoherent dedispersion methods are computationally expensive and troublesome. To deal with ... dick\u0027s sporting goods stock price historyWebThe term incoherent dedispersion refers to applying frequency-dependent time delays to the I()tf, matrix, while coherent dedispersion involves applying a frequency-dependent phase shift to the Fourier transform of the raw voltage signal.
