1. An arena test system for characterizing fragments from a warhead, comprising:
an entry panel made from a wire mesh material that allows the fragments to pass through;
an exit panel made from a wire mesh material that allows the fragments to pass through after they pass through the entry panel;
wherein the entry panel and the exit panel are arranged in a wedge configuration with a wedge-shaped air space between them;
a soft catch box located behind the exit panel such that fragments that pass through the exit panel enter a front side of the soft catch box and are decelerated within the soft catch box; and
a frame that contains the soft catch box, holds the exit panel to the front side of the soft catch box, and holds the entry panel and the exit panel in the wedge configuration when the arena test system is in use.
