摘要
阐述了两种基于多相滤波器结构的数字信道化模型,就电子对抗领域中雷达侦察接收机的实际应用,提出了一种大带宽数字信道化接收机的方案,该方案采用文中阐述的两种信道化模型级联的方式,具有瞬时带宽大,频率分辨力高等特点,能够在单片FPGA中实现。
Two structures of digital channelizing are stated here, and aiming at the application of radar reconnaissance receiver in electronic warfare, a model of digital channelized receiver with wide-band and high-resolution is raised. The model is made up of two cascading structures which are stated in the paper. It can be applied in one single FPGA.
