Abstract
To design a time delay auxiliary analysis system for array signal time delay estimation, a data acquisition system with eight channels is designed and signal acquisition experiment is carried out. A virtual instrument is selected as development tool for the analysis system design. The models included in the analysis system are waveform playback, spectrum analysis, filtering analysis and time delay analysis. Spectrum analysis and time delay estimation of the signal have been carried out with the system, and curve of the time delay vs. time is given. Research result reveals that the system is helpful in the research of time delay estimation.
