Appl. No.:

8/878124

Inventors:

Earl U. Biven - Irvine CA

Gary A. Scapellati - Huntington Beach CA

Assignee:

McDonnell Douglas Corporation - St. Louis MO

International Classification:

B64D 104
F41G 700

US Classification:

89 111

Abstract:

An intercept missile testing method which includes the steps of launching a test missile threat from a first location on a substantially vertical trajectory, e. g. , with a flight path angle greater than about 70. degree. , towards an intercept point, and launching a test intercept missile from a second location on a substantially vertical trajectory, e. g. , with a flight path angle greater than about 70. degree. , towards the intercept point. The flight paths are selected so that the test intercept missile will intercept the test missile threat exoatmospherically, at an intercept (engagement crossing) angle of less than about 30. degree. Preferably, the launch velocities and trajectories of the test intercept missile and the test missile threat are selected so that the intercept will occur exoatmospherically when the test missile threat is on a downward trajectory at a velocity of 5-8 km/sec, while the test intercept missile is on an upward trajectory at a velocity 5-9 km/sec. The first location is preferably Wake Island, Johnston Island, or Kauai, and the second location is preferably Meck Island.

McDonnell Douglas Corporation - Huntington Beach CA

International Classification:

G06F16500

US Classification:

701 3

Abstract:

A ground-based interceptor missile, part of a larger ballistic missile defense system, is provided for intercepting enemy intercontinental ballistic missiles. The interceptor employs a method based on numerical partial derivatives for computing required divert velocity corrections to remove predicted ground-based interceptor miss errors for engagement during the midcourse of the enemy missile flight.

International Classification:

F41G 700
F42B 1500

US Classification:

244 31

Abstract:

A missile intercept system using radiation sensors for guidance that can avoid intercept uncertainty due to unfavorable positions of intense radiation sources, like the sun, moon, or countermeasures flares. When the sensor viewing angle is close to such intense radiation sources, the optics on the kill vehicle may be substantially degraded or even destroyed. The potential for an "out of the sun" attack cannot be avoided when international treaties restrict each country to a single defense site while potential launch sites are proliferating about the globe. Therefore, two kill vehicles are launched when an intercept planner determines that the viewing angle from the kill vehicle to the target vehicle will be looking at or near the sun during the engagement. A surrogate kill vehicle is launched on a trajectory that will "fly-by" the target vehicle with viewing angles that will not "see" the sun. The surrogate kill vehicle then sends tracking data to the other kill vehicle for use by the second kill vehicle to guide itself to the intercept.

Abstract:

A sun-shield comprising a canopy assembly adaptable for connection to each of a variety of back-pack frames, said frames being supported on a back-packer's back, waist and shoulders. Said assembly having a canopy support frame including vertical support rods, back-pack frame adaptors, right angle members, and a coupling for interconnecting the frame adaptors and right angle members comprising the lower portion of the sun-shield to the canopy assembly comprising the upper portion of the sun-shield. Opaque canopy means, attached to the canopy support frame, prevents the transmission of light through the canopy. Foldable flap members are attached to the canopy means along the edge thereof. The canopy means is positioned to be horizontal, above and displaced from the back-packer's head for blocking out sunlight incident thereon. Said canopy support frame is easily removable from said coupling for separate storing.
