动态非均匀数字信道化接收技术研究与实现

摘要

数字信道化接收机以其高性能在电子战和无线电通信中有着重要的运用。本文介绍了一种动态非均匀数字信道化接收机的设计及实现，描述了接收机的硬件架构设计、固件设计和最后的指标测试结果。接收机采用CPCI架构进行设计，采用宽带中频采样、动态非均匀信道化、数字下变频等技术实现了对多种雷达信号的智能接收与处理。%Own to its high performance,the Channelized Digital Receiver plays a great role in EW(Electronic Warfare) and wireless communication. This article gives details about the design of a dynamically and heterogeneously channelized digital receiver. The hardware architecture of the receiver,the firmware design and the ifnal test results are described. CPCI architecture is used in the design. Due to the technique use of RF sampling,dynamically and heterogeneously channelization and Digital Down Convert,the receiver can intelligently deal with many kinds of radar signals.
