A1 Hayakawa, Masashi A1 Ogawa, Toshio A1 Komatsu, Masayuki T1 COMPARISON OF OBSERVED AND MODEL WAVEFORMS OF Q-BURSTS JF Telecommunications and Radio Engineering JO TRE YR 2010 FD 2011-02-10 VO 69 IS 19 SP 1735 OP 1750 K1 Q-bursts K1 global electromagnetic resonance AB Experimental waveforms of natural ELF transient signals (Q-bursts) are compared with model computations. Vertical electric field component of Q-bursts was recorded at Tochi, Japan (33.3° N and 33.4° E) in 2003−2005. Separate pulses were chosen recoded in fair weather conditions in a wide frequency band with the help of the "ball" antenna. The computations were performed for the uniform isotropic spherical Earth − ionosphere cavity model with the linear frequency dependence of the wave propagation constant. Pulses arriving from different distances were compared, and each pair showed a high reciprocity of waveforms. Coincidence indicates that the model applied is correct; it simultaneously shows that distances are accurate found from the time delay between the first pulse and the antipodal wave.
