Abstract:

The channelized frequency measurement model and instantaneous frequency measurement model are summarized utilizing the concept of standardized modeling.Sub-modules of Channelized frequency measurement based on polyphase filter and instantaneous autocorrelation and the instantaneous frequency measurement module based on improved phase difference are simulated respectively.A comparison is made of the pros and cons of the two modules.Simulation verifies the effectiveness and correctness of the proposed algorithm.
