Because the waveforms of seeker-eCabin have the characteristics of complexity, types diversity and high testing accuracy requirements, the comprehensive method based on wavelet analysis is proposed in this paper. It takes into account the time domain and frequency domain information of waveforms. Combining Euclidean distance and sliding window method, the similarity between testing waveforms and template waveforms is calculated. Experimental results show that the comprehensive method has an effective discrimination of waveform similarity. It solves the problem of complicated waveform similarity measuring and completely meets the demand of the automatic detection system of seeker-eCabin.
