Abstract EN
The information about the distance of separation between two-point targets that is contained in scattering data is explored in the context of the scalar Helmholtz operator via the Fisher information and associated Cramér-Rao bound (CRB) relevant to unbiased target separation estimation.
The CRB results are obtained for the exact multiple scattering model and, for reference, also for the single scattering or Born approximation model applicable to weak scatterers.
The effects of the sensing configuration and the scattering parameters in target separation estimation are analyzed.
Conditions under which the targets' separation cannot be estimated are discussed for both models.
Conditions for multiple scattering to be useful or detrimental to target separation estimation are discussed and illustrated.
