| dc.description.abstract | In this study a process of acquiring a trend of significant spectral coefficients of Photonic Doppler Velocimetry (PDV) data is proposed. The novelty of the paper is the design of a methodology which will allow to find a specific curve describing data of aluminium metal plate acceleration by detonation products of brisant high explosive obtained using PDV in time on the basis of frequency response. The paper combine short time Fourier Transform (STFT), time-frequency varying autoregressive process (TFAR) to specify the description of detonation products from both time and frequency perspectives. We also investigate the identification of a curve describing such behavior of frequency response on time in processed spectrogram. | en |
