Information on Over-the-Horizon Radar. Part 16 - Ionospheric Disturbance and HF Radar

Abstract

It is shown that backscatter propagation differs from point-to-point propagation insofar as Doppler effects are concerned. Analogously, the dispersive nature of the ionosphere also shows itself differently in the two cases. Certain F-layer disturbances are potentially troublesome to HF radar operations. One of these, which occurred during a 4-hour interval on February 11, 1958, is briefly discussed. The effect of auroral absorption on HF radar is roughly approximated for different operating frequencies and station latitudes.
