1. A target resolution analysis method comprising the steps of: illuminating a target with acoustic waves; positioning a device at multiple acoustic vector sensing positions approximate to the target in a scattered acoustic field of reflected waves; simultaneously measuring acoustic pressure and particle velocity at each of the vector sensing positions; converting with a Hilbert transform the measured acoustic pressures and particle velocities into a complex signal having active (real) and reactive (imaginary) vector components; computing active and reactive acoustic intensities at each of the vector components; and mapping decomposed scattered active and reactive acoustic intensity minimum field structures (nulls) to a bitmap representation of the target.
