摘要
提出了一种基于数字信道化的数字射频存储(DRFM)系统,推导了相应的多相滤波算法,利用内插技术实现了信号的近似重构,在传统DRFM系统基础上提出一种新的DRFM系统实现结构,该结构具有同时多信号干扰能力。最后通过Matlab仿真验证了设计方法的可行性和正确性。
This paper proposes a digital radio frequency memory （DRFM） system based on digital channelization,deduces the corresponding polyphase filter algorithm, uses interpolation technology to realize the approximate reconstruction of signal, puts forward a new DRFM system realization structure based on traditional DRFM system, which has multi signal jamming capability, finally simulates and validates the feasibility and correctness of the design method.
