摘要
为了测试电子设备的抗干扰能力,设计了一种射频信号干扰器,可用于产生406.0～406.1 MHz范围内的随机干扰、点频干扰和扫频干扰信号.设计采用了直接数字频率合成（DDS）技术,通过单片机对DDS芯片的控制,可灵活产生需要的干扰频率.
To test anti-jamming capability of electronic instruments,a RF signal jammer is designed.It can generate jamming signals of single frequency,sweep frequency and random frequency between 406.0MHz and 406.1MHz.Based on Direct Digital Frequency Synthesizer （DDS） technology,it can generate needed jamming frequency conveniently.
