摘要
数字信道化接收机具有高截获概率和处理灵活的特点,设备体积小巧,是未来通信对抗接收机的发展趋势之一。通过对低通滤波器组数字信道化实现方法进行研究,实现了实信号非严格抽样数字信道化算法的严密推导,解决了虚假信号判决及信道合并等问题,并使用Matlab仿真工具箱Simulink对算法进行了仿真,对工程的系统设计具有一定的指导意义。
Due to its advantages of high interception probability and low volume,the digital channelized receiver is the ideal communication device in the future.Based on digital channelization implementation method with LPF groups,the paper realizes un-grimly sampling digital channelization algorithm,resolves such problems as judgement of false?signals and combination of channels.With simulation toolbox Simulink,the paper realizes the whole procedure from total simulation to ground hardware design and makes suggestions for the engineering system design.
