文摘When a signal propagates in the atmosphere, a small variation will occur in its propagation direction because of refraction. The signal path will be a curve other than a straight-line. The characteristics of signal direction variation in propagation in the atmosphere are detailed, new and more precise path-curving correction formulas are derived on the basis of a new atmospheric layer-built model.
