For some limitations that currently exist about the detection and interference of the GPS signal, but also to obtain a greater advantage in the process of information confrontation, on the basis of the basic principle of the GPS signal detection and interference, assuming in the dynamic and complex environment conditions of information countermeas, the paper presents a design of signal detection and GPS signal interference by using broadband noise. Theoretical analysis and simulation result show that: the design has resulted in the frequency characteristics of the GPS signals become more volatile, and so obtain better result of detection and interference.%针对GPS信号的检测干扰,目前所存在的一些局限,同时也为了在信息对抗过程中能及时取得更大的优势,在分析了GPS信号检测干扰基本原理的基础上,假想在动态复杂多变的信息对抗环境条件下,提出了一种信号检测及利用宽带噪声进行GPS信号干扰的设计方案.理论分析和仿真实验结果表明:该方案使得GPS信号的频率特性变得更不稳定,从而得到了较好的检测干扰效果.
