    Abstract: A mechanical means for deploying one of two or more feed sources within a test range is presented. The feed source selected for testing is properly positioned for use within the range by rotating one of two or more arms to an upright and locked position. An arm may further include a rotatable antenna wheel with two or more feed sources thereon whereby a selected feed source is rotated into position via the antenna wheel. The antenna wheel includes a center body, feed sources attached to the center body and aligned along a rotational plane, and a shroud disposed about the center body and feed sources. The antenna wheel may include a cooling system for managing heat generated by the feed sources and electronics therefore. In preferred embodiments, the feed source changer is mounted within the range so that a selected feed source communicates an emitted beam onto a reflector which is redirected as a reflected beam toward a device under test. Concealment panel(s) may be positioned adjacent to the feed source changer to minimize electromagnetic reflections therefrom.

    Abstract: A landmine-neutralization system has a vehicle including a water supply tank and an electrical power supply and an electro-discharge apparatus. The electro-discharge apparatus includes one or more electro-discharge nozzles each having a discharge chamber that has an inlet for receiving water from the water supply tank and an outlet, a first electrode extending into the discharge chamber and being electrically connected to one or more high-voltage capacitors that are connected to, and chargeable by, the electrical power supply, a second electrode proximate to the first electrode to define a gap between the first and second electrodes and a switch to cause the one or more capacitors to discharge across the gap between the electrodes to create a plasma bubble which expands to form a shockwave that escapes through one or more exit orifices of the one or more nozzles ahead of the plasma bubble to thereby neutralize a landmine.
