| Abstract: | Differential interference sensor system is a new type of system, which could be used in the long-distance and strong-EMI condition for monitoring and inspection.This function turns to critical especially when it is used for a real security project in which a quick response to intrusion is a must.This paper provides a wavelet-based approach to build different burst modes and identify them, which could be used for mode identification in a real project, and the approach is proved by a large number of practical experiments. |
