Abstract

Radio pulsations observed during the 11 April 2001 event at six single frequencies 237 327 408 610 1420 and 2695 MHz by the Trieste radiopolarimeter with a time resolution 10 ms are analyzed A wavelet analysis method as well as time delay and polarization measurements are used Both methods reveal pulsations with a period of about 01 s at all observed frequencies Furthermore the 01 s pulsations drift toward higher and lower frequencies starting at about 1420 MHz The polarization of pulsations increases with frequency and time The remarkable fact that the detected 01 s period of pulsations does not depend on frequency in a very broad frequency range is discussed in terms of existing models of pulsations
