Abstract

Using Matlab’s simulink tool to model and simulate the UWB Mutirate Digital Instantaneous Frequency Measurement(DIFM) system based on DIFM’s fast Fouriour transform theory.We have built a Multirate DIFM simulating model,and it is intuitionistic,realtime and realistic,meanwhile,because of the advantage of simulation techniques,when the input signal is singlecarrierfrequency with noise,the simulation result indicates that as the input frequency is in 12GHz and 18GHz,the DIFM system has good frequency measuring performance.
