  This study investigates the applicability of Kirchhoff migration (KM) for a
fast identification of unknown objects in a real-world limited-aperture inverse
scattering problem. To demonstrate the theoretical basis for the applicability
including unique determination of objects, the imaging function of the KM was
formulated using a uniformly convergent infinite series of Bessel functions of
integer order of the first kind based on the integral equation formula for the
scattered field. Numerical simulations performed using the experimental Fresnel
dataset are exhibited to achieve the theoretical results.
