The Loss of Radio Interferometer Sensitivity Depending on the PCal Signal Parameters

Transactions of IAA RAS, issue 38, 55–61 (2016)

Keywords: radio interferometer, VLBI, PCal signals, correlator.

Abstract

The dependence of the loss of sensitivity of the radio interferometer with bandwidth up to 1 GHz DBBS from the parameters of PCal signals (power and frequency density) is determined. The accuracy of calculating the PCal delay in the receiving channel of the radio telescope and the necessary accumulation time for the PCal phase determination are estimated.
