Abstract:Passive radar has recently received attention due to its advantages like low cost, covert operation, and difficulty of jamming. With cognition ability added in, passive radar's performance can improve for its adaptability to the environment. In this paper, multi-illuminator compatible cognitive passive radar, which aims at future complex electromagnetic environment and best potential illuminators selection, was proposed and well designed. The new structure improves robustness and adaptability compared to the single-scheme passive radar system. The proposed novel cognitive passive radar architecture provides a guideline on where and how to carry out further research on dealing with the complex and heterogeneous problem of future sources of opportunity. | |||

Abstract:ISAR imaging is an important imaging method of radar imaging, which is widely studied. Firstly, the paper describes the principle of ISAR imaging with Range-Doppler method using chirp signal. Based on this, the paper put forward the sub-aperture imaging algorithm based on moment invariants. Moment invariants have been widely applied to image pattern recognition in a variety of applications due to its invariant features on image translation, scaling and rotation. The method can obviously improve the imaging quality, shorten the imaging time. Finally, the computer simulations with aircraft model are carried out. The simulation results show the feasibility and validity of the method. | |||
