Summary form only, given. A series of chamber experiments was conducted to investigate three major issues concerning the feasibility of using microwave-produced atmospheric plasma layers as a supplemental reflector for the OTH radar. These include (1) the effectiveness of the plasma layers as a Bragg reflector, (2) the propagation of high-power microwave pulse, and (3) the lifetime of the plasma....
Summary form only given. When a high-power microwave pulse propagates in air with a breakdown threshold below the wave field of the pulse, the ionization of the air will occur. The electrons produced will attenuate the field amplitude at the tail portion of the pulse. If the electron density reaches the cutoff density of the microwave pulse, the reflection caused by cutoff will even cause severe tail...
