SWING
Fig. HF signals propagation - these signals can propagate via: Ground-wave for short distances (up to 100 km over land and 300 km over sea). Sky-wave in single hop (the e.m. wave reaches the receiver after a single ionospheric reflection) and/or multi hop (the e.m. wave is reflected by ionosphere with intermediate reflections on the Earth’s surface)
Fig. Reference scenario and HF link connections among ECIs (European Critical Infrastructures) and CGAs (Controlling Governmental Agencies)
Fig.3 Physical topology of the SWING network
Fig.4 The use of ray-tracing algorithm combined with the Watterson’s model allows reconstructing the e.m. path; specifically the coloured background (a) refers to the electron density content while the white line represents the ray-paths between transmitter and receiver (b).
