Abstract: The horn structure (22) is composed of a vertical array of horn pairs (26A-26G) arranged in stacked relationship to each other. The horns (27L and 27R) of each pair have entrance openings (40L and 40R) at the same elevation and disposed side-by-side to each other. The mouths (50L and 50R) of the horn pairs are in directional alignment with each other and stacked vertically on top of each other.

Abstract: The acoustic horn manifold (22) is composed of a vertical array of horn pairs (26A-26G) arranged in stacked relationship to each other. The horns (27L and 27R) of each pair have entrance openings (40L and 40R) on first common plane 44 and at the same elevation and disposed side-by-side to each other. The mouths (50L and 50R) of the horn pairs are in directional alignment with each other and stacked vertically on top of each other. The mouths may be laterally offset somewhat from each other and/or may extend forwardly from respective horn entrances at different distances from each other.

Abstract: A projector of multiple skewed light planes or sheets is located adjacent a vehicle to be protected and detectors are arranged to defect the penetration of the light sheets by an incoming object, with the time intervals between the piercing of the planes defining the path of the incoming object and its expected impact time. An array of bullet-firing barrels is arranged to project bullets in ah iron curtain under control of a fire control module that fires a round in a barrel above the projected flight path such that the round impacts the nose of the object and disables it. It is thus the piercing of the skewed light sheets mat provides information as to the impact point of the object as well as its time of arrival so that a round can be fired to intercept the object as it arrives at the iron curtain.
