摘要
A target analysis method that includes the steps of: illuminating a target with acoustic waves; positioning a device at multiple acoustic vector sensing positions about the target in a scattered acoustic field of reflected waves to simultaneously measure acoustic pressure and particle velocity at each vector sensing position; converting using a Hilbert transform the measured acoustic pressures and particle velocities into a complex signal having active real and reactive imaginary vector component; computing respective active and reactive acoustic intensities at each vector components; and mapping field structure nulls being zero crossings of the active and reactive intensities to a bitmap representation of decomposed scattered target acoustic intensities of the target.
