Indoor imaging scenarios involving complex environments are studied by utilizing a combination of ray tracing and imaging algorithms. The utilized ray tracer is based on computing equivalent sources on a Huygens surface, which can be placed arbitrarily between the antennas and the considered scattering objects. To verify the simulation results we compute synthetic aperture radar (SAR) images for several configurations by utilizing an inverse source based reconstruction algorithm and compare the results to those obtained by a standard backprojection algorithm.
