摘要
通过建立分析实信号数学模型,从系统设计角度研究中频采样后直接进行实数信道化的实现方法。理论和实测数据分析表明新的处理架构使用资源更少,更利于工程实现。为了进一步减少计算量,还重点分析了一倍采样下瞬时测频解模糊方法,对工程运用具有较强的指导意义。
The channelization of real numbers can be realized directly after IF sampling from the perspective of system design by establishing and analyzing the mathematical model of real signals.Theoretical and measured data analysis shows that the new processing architecture uses fewer resources and is more conducive to engineering implementation.In order to further reduce the amount of calculation,the instantaneous frequency measurement ambiguity resolution method is analyzed emphatically under double sampling,which has strong guidance for engineering application.
