An optimization procedure for signature reconstruction of near-field targets

In this paper, a target reconstruction procedure is proposed for simulating the near-field signatures of a complex target with high fidelity. The target model is composed of trihedral corner reflectors and different radar targets can be represented by combinations of trihedral corner reflectors without manufacture of either full-size or scaled target models. The near-field target is initially reconstructed based on the synthetic radar image. An optimization procedure is proposed to improve the performance of such target model. Simulation results show that the aspect-variant scattering characteristics of the target model maintain good agreements with that of the true target.
