Abstract: | In this paper, we describe pulsar observations at decametric wavelengths using the Gauribidanur Radio Telescope made subsequent
to our earlier measurements (Deshpande & Radhakrishnan 1992). To improve the time-resolution in our measurements of pulse
profiles, we have used the ‘swept-frequency dedispersion’ method with some modifications to suit its application at such low
radio frequencies. We also present a new scheme that simplifies the calibration of the receiver gain characteristics. We present
average profiles on four pulsars from these improved measurements at 34.5 MHz. |
