摘　　要：文章设计了一种GPS干扰器，利用锁相环频率合成技术和二极管产生噪声的方法，将噪声信号引入到压控振荡器（VCO）的调谐端，从而可生成GPSL1工作频率上带有噪声的信号，该输出信号频率稳定、具有2MHz带宽，并且具有一定的输出幅度。该干扰器可以用来干扰GPS导航接收机，试验表明在一定范围内干扰效果良好。This paper designs a GPS jammer. By means of the phase-locked loop frequency synthesis technology and the method for generating noise with diode, the noise signal generated by diode is introduced into the tuning port of the VCO to generate noised signal in GPS L1 working frequency. The output signal with 2 MHz bandwidth has the performance of stable frequency and a certain outout amolitude. The jammer can be used to jam GPS navigation receiver, and the tests indicate that the jamming effect is good within a certain range.
