| Abstract: | Using the basic theory and method of time-frequency analysis,the time-frequency distribution of PD radar transmitted signal effected by different pulse width,different pulse repetition frequency and different simple frequency is analyzed.And then the time-frequency distribution of PD radar received signal effected by different target distance,different target velocity,different target accelerated velocity and different target reflection intensity under noise background is analyzed.Moreover it is emulated by MATLAB time-frequency toolbox. |
