摘　　要：在通信对抗中,频率非等间隔的干扰信号可以有效地对敌方跳变频电台实施干扰。针对频率非等间隔梳状谱干扰信号峰均功率比(PAPR)较高的问题,从相位优化的角度出发,提出了一种降低频率非等间隔梳状谱干扰信号PAPR的新方法,通过最速下降法寻找一组能够降低频率非等间隔梳状谱干扰信号的PAPR的最优初始相位组合,仿真结果表明该方法能够有效抑制频率非等间隔梳状谱干扰信号的PAPR。In the field of communication countermeasures, the enemy ＂s frequency- hopping broadcasting station can be interfered effectively by unequal interval comb spectrum jamming sig- nal. From the perspective of phase optimization, a new method is given to suppress the peak to average power ratio （PAPR） reduction of unequal interval comb spectrum jamming signal. The steepest descent method is used to search the optional initial phase of unequal interval comb spectrum jamming signal for PAPR reduction. Simulations show that the PAPR of unequal inter- val comb spectrum jamming signal is inhibited by conjugate-gradient method algorithm.
