Abstract:
Observations of groups of pulses closely spaced in frequency which had propagated through the auroral zone were made in order to determine the pulse fading correlation bandwidth. Transmissions were made at various times of day on frequencies near the FOT and with pulse lengths of 100 microseconds and 1 millisecond. Fading correlation bandwidths for radio paths of 4500 and 5700 km which cross the auroral zone were found to range from 2 to 6 kc/s and were much less than a bandwidth of near 60 kc/s measured on a 2400 km non-auroral path.
