Abstract(in Japanese) (See Japanese page)
Abstract(in English) The computerized method for predicting the LF/MF field strength is developed. It provides not only sky-wave components but also resultant field strengths of 1-and 2-hop sky-wave and ground-wave received over the ground ranges up to 4000 km covering frequency ranges from 40 to 500 kHz. The temporal variations of field strengths and phase angles received at a fixed point are also calculated. The field strength predicted with the method shows good agreement with values measured at Koganei where JJY 40 kHz and 60 kHz standard frequency waves are being received.
