摘要: 基于数字式瞬时测频(DIFM)的傅立叶变换法原理,利用Matlab的Simulink工具对超宽带多速率瞬时测频接收系统进行了建模与仿真。在输入信号为噪声干扰的单信号情况下对其测频性能进行了模块化仿真,同时用GUI工具做了一个频率解模糊程序验证了系统输出。仿真结果表明,该方案的接收系统在输入信号频率为12GHz~18GHz范围内能实现准确测频。

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.

Key words: UWB;bandpass sampling; DIFM;software radio
