Abstract: The classification of human activity using radar has gained considerable attention in recent years because of the radar sensor’s resistance to harsh settings. However, when using machine ...
短时傅里叶变换（STFT）可以有效地处理非平稳数字信号，给出瞬时频率的信息。STFT的本质就是将一段信号截成多段，对每一段进行单独傅里叶变换（FFT），最后在时域上接起来，就形成了STFT的 ...
