Abstract :
An Over-The-Horizon Radar (OTHR) has been deployed near Ottawa, Canada. The radar is aimed northward and collects auroral echoes through line-of-sight propagation and ground echoes from beyond the horizon through ionospheric reflection. These echoes have been resolved in the three spatial dimensions of range, azimuth, and elevation, as well as in the temporal dimension of Doppler. It is shown that the three-dimensional spatial resolving capability is useful for separating the auroral and ground echo components.
