Within the framework of Maxwell equations mathematical models of distribution of flat one-dimensional electromagnetic waves in cases when the radiator and reflectors move be relative each other, being in the same system of coordinates, are received. Models represent boundary Cauchy problems of the equations of hyperbolic type. Analytical decisions of problems are found by a method of characteristics. Results of the decision reveal existence of two kinds of Doppler Effect named radiated and reflected. Radiated it is found out by the motionless receiver as a result of reception of the signals reflected from motionless reflectors, irradiated with a moving radiator. Reflected it is found out by the motionless receiver combined with a radiator, as a result of reception of the signals reflected from moving reflectors.
