摘　　要：现代作战中,电磁侦查技术日益先进。虽然使用电台通信容易造成导弹定位、行踪暴露等后果,但充分利用电台通信暴露问题,设置伪电台、假目标,可以达到良好的战术欺骗效果。因此,设计一种伪电台专用化的射频数字化短波激励器,其结构简单、集成度高、保密性强,并给出了激励器的硬件与软件设计过程。将PC作为收发编解码、调制解调终端,设计的激励器作为主要发信设备,短波收信机为接收设备,并在短波频段上实现报文的发送与接收,从而验证了射频数字化短波激励器的功能。In modern warfare, electromagnetic detection technique becomes increasingly advanced. Although radio communication could easily cause the missiles to be positioned, whereabouts exposed and so on. However by making full use of the problem exposed by radio communication and setting up pseudo radio or false target, the good effect of tactical deception may be reached. For this reason, a specialized radio frequency digital HF exciter for decoy HF radio is designed, being simple in structure, high in integration and strong in security,the design processes of hardware and software are also given. With PC as a encoding and decoding, modulation and demodulation terminal, the designed exciter as transmitting device,HF receiver as receiving device, and realizing message transmitting and receiving in HF,the function of this HF exciter is thus verified.
