Abstract:

High frequency radio wave propagation studies at Goose Bay, Labrador and between Goose Bay and an instrumented KC-135 aircraft are discussed. Both power- and phase-coherent detection schemes were applied to investigate the coherence of the ionospheric echoes. Backscatter ionograms were recorded in this dynamic environment using digital power-integration techniques. Stable synchronization between the ground station and the aircraft enabled the recording of swept frequency oblique ionograms over distances of up to 3000 km. Alternating with vertical and oblique incidence ionograms, Doppler and angle of arrival measurements were carried out at the ground on multiple fixed frequencies transmitted with the aircrafts Digisonde-drift system.
