Abstract : A large, sampled-aperture antenna array has been constructed near Ottawa, Canada, for the high resolution study of HF radio propagation. This new system permitted the measurement for the first time of detailed RF phase characteristics of the diffraction pattern formed on the ground by radio waves obliquely reflected from the ionosphere. Swept frequency continuous wave (SFCW) signals were used, so that the received signal could be separated on the basis of propagation delay into components or modes.
