Today, the ramark beacon signals seem to remain just the bearing information. They will be much more valued, however, if their signals bring the navigators the land-fall distance information at which the bearing sweep appears on the rader scope first time, just likely to beams of the light-house, because, the navigaters rapidly may fix her potition easily at that time. Regarding the propagation of the ramark microwaves as those in diffraction region beyond the curvature of the earth, the author studied the estimation method by calculation the diffraction field on the Bullington Nomograph. The practical sea experiment held at Sata and Nojima, Misaki approaches have pvored this method approximately available.
