Fast Radio Burst Search: Cross Spectrum vs. Auto Spectrum Method
arXiv:1802.03137 · doi:10.1088/1674-4527/18/6/69
Abstract
The search of fast radio burst (FRB) is a hot topic in current radio astronomy study. In this work, we carry out single pulse search for a VLBI pulsar observation data set using both auto spectrum and cross spectrum search method. The cross spectrum method is first proposed in Liu et al. (2018), which maximizes the signal power by fully utilizing the fringe phase information of the baseline cross spectrum. The auto spectrum search method is based on the popular pulsar software package PRESTO, which extracts single pulses from the auto spectrum of each station. According to our comparison, the cross spectrum method is able to enhance the signal power and therefore extract single pules from highly RFI contaminated data, which makes it possible to carry out FRB search in regular VLBI observations with the presence of RFIs.
