| Abstract: |
Pre-detection, or ``coherent,'' dedispersion is a powerful technique which completely eliminates the effects of dispersive smearing on pulsar profiles, greatly increasing the precision of timing and polarization observations. Various software and hardware implementations of this method are described. Polarization observations with filterbanks and with coherent dedispersion are discussed, including calibration and compensation for instrumental effects. Finally, the technique of pulsar timing is presented, with descriptions of the method for obtaining pulse times of arrival and the software used to fit models of the pulsar's spin-down behavior, and a broad overview of scientific goals. |
