Remote localization of a moving target in a random scattering medium based on the Born approximation

This paper presents a technique to remotely localize a moving target embedded in a fixed multiple scattering medium. The method, based on the Born approximation, does not require full modeling or even a moderately detailed knowledge of the multiple‐scattering background. Using a multi‐source/receiver laboratory setup in air, the technique was tested with experimental data at frequencies varying from 30 to 60 kHz (wavelength ranging from 0.5 to 1 cm) for centimeter‐scale scatterers in a multiple scattering medium with 3% volume fraction. The method shows very good localization of the target with a precision of a few wavelengths.
