Figure 6. Comparison of the reflectivity profiles along elevation direction reconstructed by MAP (blue) and SLIMMER 
(red) using the data stack of TSX (left) and TDX cases (right). The true elevations of the two scatterers are 10 and 25 
meter, respectively, an i.e. elevation distance is 0.4 times of the Rayleigh resolution limit.

Figure 7. Estimated elevations [m] of two scatterers of equal reflectivity of increasing elevation distance. Shown are the results 
of MAP, (a), (d), NLS estimation (b), (e), and SLIMMER (c), (f). Upper plots: TSX case; lower plots: TDX case. The true 
positions are a horizontal line referring to the ground and a diagonal line referring to the scatterer at variable elevation. 
(Blue: detected single scatterer; red: detected two scatterers)
