Abstract: A high energy, e.g., ultraviolet (UV) catalyzed decomposing foam encapsulating kinetic media forms a payload to be boosted in space and provides an ultra-light weight means for intercepting an incoming missile or other target. The decomposed foam releases the kinetic media (at designed rates so as to preserve a required density of media on target) to intercept a target and destroy it. The use of the decomposing foam significantly lowers the weight and cost and improves the probability of success of destroying the target.

Abstract: A tunable and aimable artificial lightning producing device for tetanizing human voluntary muscle, disabling vehicular electronic ignition systems, and for pre-detonating wired explosives. A spark gap shaping apparatus controls a spark generated by a Tesla coil. A first stage directionalizer warps a normally spherical plasma field from the Tesla coil into an oval plasma field for confining the spark to within that shape. A second stage directionalizer converges multiple beams to successive points just ahead of a plasma field created by the first stage directionalizer without ionizing the beams, thereby maintaining ionization of a path of the spark. The spark is progressively arced to these points, thereby maintaining the path of the spark.

Abstract: The present invention provides a MKV interceptor including multiple kill vehicles with autonomous management capability and kinematic reach to prosecute a large threat extent. Each KV can self-manage its own KV deployment and target engagement for a determined target volume assigned by a designated master KV. At least one KV is master capable of managing the post-separation of all of the KVs without requiring updates to the mission plan post-separation. The autonomous capability and increased kinematic reach provides for a more efficient use of boosters and more effective engagement of the threat.

Abstract: By sharing tasks between the CV and the KVs, the MKV interceptor provides a cost-effective missile defense system capable of intercepting and killing multiple targets. The placement of the acquisition and discrimination sensor and control sensor on the CV to provide target acquisition and discrimination and mid-course guidance for all the KVs avoids the weight and complexity issues associated with trying to “miniaturize” unitary interceptors. The placement of a short-band imaging sensor on each KV overcomes the latency, resolution and bandwidth problems associated with command guidance systems and allows each KV to precisely select a desirable aimpoint and maintain track on that aimpoint to impact.

Abstract: An Unmanned Aerial Vehicle (UAV) system that couples the speed and responsiveness of a shoulder-launched rocket with the stable, slow-moving aerial platform of a parafoil is disclosed. The unique use of an over-damped rocket automatically positions the parafoil upwind of its target and overcomes the inherent inability of the parafoil to make headway in adverse wind conditions. This marriage of a rocket and a parafoil creates a valuable new synergy that allows the rocket to very quickly position a payload at altitude and defeat any adverse winds, while the parafoil provides an inexpensive and easy-to-fly vehicle for reconnaissance or accurately placing a payload on a target. The system is suitable for aerial videography, thermal imagery, target designation, sensor placement or precision munitions delivery; and can perform these functions at a small fraction of the cost of any other UAV. Unlike other UAV's, no flying skills are required of the operator.

The JAR and JAS graphics and text will aid the EA aircrew in rapidly assessing the effectiveness of a given jamming approach.

Abstract: A method guides an interceptor missile toward an accelerating target. The method sets up a line-of-sight between the interceptor and the target, and monitors the acceleration of the angle of the line-of-sight. The acceleration is multiplied by a gain factor dependent upon the range between the target and the interceptor, to generate a driving acceleration. The acceleration of the interceptor in a direction perpendicular to the line-of-sight is added to the driving acceleration, to generate pre-weighted acceleration. The pre-weighted acceleration is multiplied by a navigation factor to produce commanded interceptor acceleration.

The identified rocket type and likelihood is used to aid in determining the future location of the missile so countermeasure can be applied.
