Research on the Identification and Measurement of Coupled Source Signals of Electromagnetic Orbital Accelerators

Aiming at the interference problem of multiple signals generated by the coupled source of orbital electromagnetic kinetic energy accelerator on the acquisition of measuring instruments, a generative Heterogeneous of wavelet Transform (GHT) method is proposed, which combines the characteristics of different physical quantities to map the collected data waveforms into the generated heterogeneous space, and accurately identifies and measures complex signal waveforms. Firstly, a set of multi-physics coupling field shock signal waveforms were collected by electromagnetic kinetic energy acceleration test, and the waveform decomposition accuracy indicators (DAM) of STFT, CWT and GHT were compared to define the signal decomposition accuracy metrics (DAM), which verified the decomposition characteristics of GHT on complex shock waveforms. Secondly, the one-dimensional time-domain waveform is converted into a two-dimensional time-frequency domain image, and an Image classification of seed growth clusters (ISGC) is established, and the results show that GHT can decompose and filter the signal image with impact noise signal, current signal and speed signal interference to obtain a clearer pulse waveform, which proves the correctness and feasibility of the proposed method.
