Applied Technology in Multi-Frequency Eddy Detection Signal Processing Using Kalman Filter

Abstract:

Based on the Kalman filter, A multi-frequency eddy current signal demodulation method is proposed. By directly sampling the analog signal of multi-frequency eddy system, the multi-frequency phase and amplitude information of eddy current will be obtained by the proposed method immediately and synchronously. Contrasting the traditional method, the proposed method does not need hardware demodulation circuits and the circuit structures are also simple. Moreover, the proposed method is more flexible, which may be configured to any frequencies parameters by software way and no longer dependent on specific hardware circuits.
