2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE).
Incoherent scatter radar (ISR) detects the Thomson scatter echo of free electrons to inverse ionosphere parameters and is thought as the most powerful instrument to observe the ionosphere on the ground. In fact there are usually severe ground clutter

In this work, carbon nanotubes (CNTs) were introduced into an impact polypropylene copolymer (IPC) with β-nucleating agent to prepare IPC composites just by means of a simple mechanical blending method without any special treatment of the CNTs. The

To find a better rotating retrodirective cross-eye jamming system, a new scenario is presented, which consists of four retrodirective jamming elements. A new criterion called “stability factor” is proposed to evaluate the ability of cross-eye jam
