- Abstract:
- For acoustic measuring of gas temperature and flow, firstly, a processing method for microphone received signal based on the matched filtering with the pre-whitening to the AR modeled noises achieves good performance, in order to identify the time-of-flight under noise contamination. Then, the PRK (phase reversal keying) of the M-sequence appears to be proper for the testing signals, which are sent into the object. Finally, this system is validated through experiments.
