Abstract

We propose a forward-looking ground penetrating radar using laser produced-plasma channels. The plasma channels work as a microwave guide to and from the buried objects. In order to confirm this method's feasibility, we investigated the propagation properties of plasma channels.

Keywords

forward-looking ground penetrating radar, sensor technology, laser plasma channel, microwave waveguide, propagation gain
