Using multi-channel displacement signal acquisition, the basic types and characteristics of the various signals in the missile are established. The extraction of the characteristic quantities enables the recognition of the redundant signals and other noisy signals. According to the method of time difference analysis and the waveform characteristics displayed by each channel, the area where the excess material is located can be qualitatively determined. This technology through the development of signal acquisition system, the signal characteristics of excess displacement signal and complex noise law analysis and research, the use of excess material positioning technology, developed a set of on-site tactical missile detection of excess material testing device, signal acquisition System, analysis and identification and positioning software to improve the sensitivity and reliability of the inspection of excess material.
