Abstract
The effect of plasma on mono-static radar cross section under atmospheric pressure is demonstrated when the dielectric barrier discharge actuator has plasma layer. The volume of plasma layer is increased by using planar array of electrodes. Because the incident wave has electric field which is perpendicular to the electrode array, the undesired effect on radar cross section caused by structure of plasma actuator is minimized. In experiments, mono-static radar cross section is measured at the frequencies from 2 GHz to 25 GHz. The generated plasma reduces the radar cross section at frequencies above 18 GHz, and the amount of reduction reaches to 8 dB in maximum. The reduction can be controlled by changing the peak-to-peak voltage from high voltage generator. The result shows the possibility of plasma as a flexible radar cross section controller.
