Abstract

Metamaterial and electromagnetic band gap (EBG) surfaces exhibit reflection phase characteristics that are different than perfect electric conducting surfaces. The reflection phase can contribute to enhancing the gain of an antenna placed on the top of such surface. It also contributes to changing the radar cross section of the object that is covered with the active surface. This characteristic may have applications in cognitive radar systems. It also has applications in radar jamming systems. The adaptive reflection phase off the active surface may be used to introduce false target information in high range resolution (HRR) radar and other high resolution imaging radar.
