“…As expected, the reconstruction for the object closer to the observation points is sharper than for the other one, which underestimates its size. The obtained results are in accordance to limited aperture experiments obtained for other model problems by either using topological derivative-based methods (see [2,14,15,34,42]) or by other techniques like the (generalized) linear sampling, factorization, or MUSIC algorithms (see [3,4,6,37])…”
