Fig. 5.4 Schematic diagram of X array
Fig. 5.5 Localizing effect of X array
5.3 Localization of Beamforming with Inaccurate Wave
Velocity
5.3.1 The Proposal of Vertical Line Method
It can be seen from the above experiments, beamforming has a good localizing effect,
but it requires a high accuracy of localization speed and good sensor positions, if
