摘　　要：针对目前欺骗干扰信号模型单一,现有DRFM系统寄生信号分析方法存在计算量大、结果不准确等问题,结合相位量化DRFM的工作原理,建立基于相位量化DRFM的欺骗干扰信号模型,将相位量化过程利用数学模型加以描述,并分析相位量化DRFM系统的寄生信号性能,对寄生信号在频谱中的位置进行定位,为干扰检测提供线索,最后利用仿真实验验证频谱分析的正确性。Currently, existing model of deceptive jamming signal is unitary while methods to analyze DRFM spurious signal have problems of large calculating quantity and low result accuracy. In order to solve these problems, a model of deceptive jamming signal based on phase quantization DRFM is built. The operating principle of DRFM is utilized and procedure of phase quantization is elaborated using math- ematical model. The spurious signal performance of phase quantization DRFM is analyzed as well. The location of spurious signal in frequency spectrum is presented and the clue is offered to detect jamming signal. Finally, experimental results show validity of the analysis.
