Intermediate frequency processing circuit of reconnaissance receiver based on polyphase decomposition

为满足在侦察接收机中实现宽带监视、窄带输出,降低对硬件运算速度的要求,提出了一种基于多相滤波结构的侦察接收机中频处理电路.该电路在实现宽带监视、窄带输出的同时,能够降低对硬件运算速度的要求.

In the reconnaissance receiver, to realize wideband surveillance and narrowband output and reduce the requirement of hardware processing speed, this paper presents the intermediate frequency processing circuit based on pol realize wideband yphase decomposition, which can reduce the requirement of hardware processing speed and surveillance, narrowband output at the same time
