| Abstract: | The theory and implementation of an adaptive window length time frequency analysis method based on the improved B distribution were presented.The method was used to analyze the in-pulse characteristics of pseudo-code fuse signals,such as pseudo-code phase modulation(PCPM) signal,combined pseudo-code phase modulation and sinusoid frequency modulation(SFM) signal,and combined pseudo-code phase modulation and linear frequency modulation(LFM) signal.The simulation result shows that both the characteristics of c... |
