Incoherent Migration for Near-Field Imaging by Uncharaterized Antennas

In this paper we present an incoherent migration (IM) algorithm for near-field reconstructions and without knowing the antenna’s response. An analytical study is presented to compare the achievable performance by IM against its coherent counterpart. Numerical examples employing two different type of antennas whose responses are not accounted for in the reconstruction process show that IM does not suffer from antenna uncertainties.
