Cramér-Rao Bound Study of Multiple Scattering Effects in Target Separation Estimation

Figure 5

Map of the regions where multiple scattering effects do not aid the estimation of target separation in relation to blind conditions of the Born approximation model. Black lines mark conditions where 𝐼_Born(𝑑)=0. Gray areas mark regions where 𝐼(𝑑)≤𝐼_Born(𝑑). The same parameters are used here as in Figure 3 (𝜏₁=𝜏₂=1, 𝛽=𝜋−𝛼, 𝑑₁ is known).
