摘要
提出了一种新的信道化IFM接收机的实现方案,该方案基于多相滤波的信道化技术,利用瞬时自相关方法实现复信号的瞬时频率测量,不仅可以实现精确的大动态范围瞬时频率测量,而且具备多信号同时处理能力,仿真结果和性能分析验证了本方法的有效性。
A new scheme of channelized IFM receiver based on the technology of polyphase filter banks is presented, which has the ability of simultaneous signal processing and fine frequency measurement within wide dynamic range using instantaneous auto-correlation technology. Finally simulation and performance analysis illustrate that the scheme is effective.
