Due to the linear formulation of their algorithms, many inverse synthetic aperture radar imaging systems are known to produce artifacts in case of monostatic setups with multiple interactions at the scatterer. Bistatic systems, where transmitting and receiving antennas are separated, may avoid this problem and are therefore of high interest. Considering relatively small bistatic angles, it is shown...
A new accelerated method for generating a fully polarimetric 3-D image of an arbitrary current distribution is proposed. The sampled farfield radiation pattern is sufficient for the reconstruction of the image. The algorithm is based on a coherent summation of the fully polarimetric plane wave spectrum. The processing of the spectrum is accelerated by a Multi-Level Fast Multipole Method-inspired hierarchical...
