摘要
针对直接序列扩频接收机的特点,研究了GPS接收机的解扩过程对干扰信号的影响,分析了干扰信号的频率与对接收机干扰效果的关系,从而解释了不同频率干扰的作用机理及干扰效率的差别。最后通过对GPS接收机的干扰实验验证了分析的正确性。
The effect of the de-spread processing to the jamming for the GPS receiver is studied. The different effect of the jamming with different frequency is researched to explain the different jamming characteristic and efficiency. The jamming experiment for the GPS receiver validates the analysis and the conclusion.
