Hello author, when I look at your DataProcess.m file in AHAR-I-DataProcessing, I found that there is a data_stft function missing in it, where is it? Thank you

We have included the data_stft.m in AHAR-I-DataProcessing now, thanks for checking this.

In this work, the usage of CVD aims to reflect the differences in the energy distribution of periodic behavior across frequency cycles. CVD represents a two-dimensional spectrogram from frequency to frequency, rather than a time-frequency spectrogram. This distinction holds significant physical meaning compared to a micro-Doppler spectrogram. I would recommend carefully reading the relevant descriptions in my text and exploring existing works on radar UAV recognition to gain a deeper understanding of the significance of CVD.If this work proves to be useful, please consider supporting and citing it. Thank you.

Can I confirm if the CVD you received is a micro-Doppler feature?
