Cross-term rejection in the Wigner-Ville distribution for velocity estimation of a narrowband sound source
《Chinese Journal of Acoustics》2022年第4期314-328,共15页ZHANG Boxuan YANG Yixin GUO Xijing 
supported by the National Natural Science Foundation of China(11974286,51679204);the Fundamental Research Funds for the Central Universities。
The Doppler shift of sound waves is widely used to passively estimate the velocity of a narrowband moving source by a single sensor.The performances of these techniques largely depend on the instantaneous frequency es...
