The invention discloses a direction modulation method for realizing random disturbance by utilizing a unit antenna. The method comprises the step of causing distortion of constellation points in an unexpected direction to randomly vary without the noise through randomizing the emission weighting coefficients of the unit antenna. Compared with the method of modulating a signal generating fixed distortion in the unexpected direction in a phased array direction, the method disclosed by the invention has the advantages that the difficulty in stealing information through tapping a receiver is increased, and the communication reliability is improved. In an expected direction, the method ensures the nondistortion of the modulated signal, so that the expected receiver can correctly receive demodulation information. The direction modulation method is independent of the variety of antenna arrays, and can be widely applied to various antenna arrays, such as a linear array, a circular array and a rectangular array.
