两通道多级信道化接收机的设计

摘要
为满足测向接收机对两个同时到达的不同带宽雷达信号的测量和跟踪需求,提出了一种双通道、多级信道化的高效宽带数字接收机结构,该接收机采用了宽窄两种带宽、奇偶两种信道排列形式,三级信道化结构的方案。经过三级的频带分割可提供多种频率分辨率,可以适应不同带宽信号的输入,改善了单级信道化同时处理窄带信号和宽带信号的性能局限性,并通过有效信道检测机制实现了对两个同时到达的不同带宽的雷达信号的接收跟踪。仿真结果表明,该双通道多级信道化接收机功能正确,具备硬件实现的可行性。
To meet the demand of the direction finding receivermeasuring two radar signals,two different radar signals arriving simultaneously andhaving different bandwidths.Proposes a dual-channel multistage channelized receiver,it has high efficient digital receiver structure.The receiver uses two bandwidths;two types of channels are arranged in the form of parity,three-stage channel structure.It may provide a variety of frequency resolution after three band division.It may adapt to the different bandwidth input signal.Compared with the single-stage channel scheme,it improves the processing capacity of two different radar signals arriving simultaneously andhaving different bandwidths.And through the effective channel detection mechanism,it can receive two different radar signals arriving simultaneously and having different bandwidths.The simulation results illustrated the validity of the dual-channel multistage channelized receiver.
