| Research Abstract |
A system to measure the propagation distance of HF broadcast radio waves was developed with digital software radio receivers by utilizing a passive radar technique. The propagation time of HF broadcast radio waves from Australia to Japan across the magnetic equator was measured by the system to derive propagation distance. A rrival angle s of the radio waves were measured simultaneously by an HF direction finder. It was suggested that more accurate position estimation of plasma bubbles and an effective wide-ar ea monitoring system of plasma bubbles would be achievable by measuring the distance and arrival angle of trans-equatorial HF radio wave propagation simultaneously.
