frequency-time spectral density function
解釋
頻率時間譜密度函數-
The basic concepts of second - order coherence theory in describing wavefields are introduced. these concepts are the cross - spectral density function and spectral degree of coherence in the space - frequency domain, and the mutual coherence function and the complex degree of coherence in the space - time domain
