Excitation, propagation and reception of wave pulses in the vicinity of the lower oblique resonance in the OEDIPUS-C experiment

The observations in the OEDIPUS-C two-point experiment of pulses of 100-kHz wave trains are presented. The waves propagate near the lower oblique resonance cone over a distance slightly higher than one kilometer in the auroral ionosphere between the emitting and receiving payloads. The interpretation of these data requires an innovative approach that takes into account both the excitation and reception of these waves under resonance conditions as well as the spreading of pulses during propagation.
