Observation of Doppler frequency shift and time of flight of a Morse code propagating through ionosphere
Takashi Iwamoto, Mao Konishi (Mitsubishi Electric) SANE2022-36
Abstract (in Japanese) (See Japanese page) 
(in English) High frequency radio wave is known to deform during propagation through ionosphere. Precise observation of its deformation is expected to bring us an estimation method of ionosphere along the way of propagation. In this report, targeted on major deformation of frequency shift, observation of a Morse code, originally transmitted from Taiwan with power of 1 Watt, sampled in Ishigaki island in Japan after propagation through ionosphere, is presented. Observation restriction by effects including power ratio of signal to noise, signal duration, and modeling error of wave form is also considered.
