Aiming at the limitation of existing frequency hopping pattern generation method, this article proposes a method for frequency hopping pattern generating on a discontinuous frequency band. Based on frequency hopping interval and uniform distributed frequency hopping pattern constraint, the method provides a uniformity compensation frequency distribution function, generate required random frequency hopping pattern according to frequency point and distributed function. Experiment results show that the method can generate frequency hopping sequence satisfying the frequency hopping interval under the condition of discontinuous frequency band, and satisfy the uniform characteristics of frequency points.
