Abstract

The disturbed narrow band channel (3 kHz) was characterized by measuring its scattering function using a channel sounder known as DAMSON (Doppler And Multipath Sounding Network). Results from DAMSON demonstrates that its use for making measurement are pertinent to HF systems operating in the high latitude region, while mean 24 hr, all frequency Doppler spreads, at a signal to noise ratio of 10 dB or higher are 5 Hz, this increases to 7.5 Hz in the time window 18 to 24 UT. Lower frequencies exhibit still bigger Doppler spreads. An illustrative operating frequency of 4 MHz, the mean Doppler spread is 20 Hz in the post midnight sector. The DAMSON system is described in more detail.
