    Abstract: An electromagnetic coil gun system includes a launcher having a barrel with a longitudinal bore therethrough, and a plurality of longitudinally extending electrical excitation coils arranged circumferentially around the bore of the barrel so that a magnetic field produced by an electrical current in each electrical excitation coil penetrates into the bore. Each electrical excitation coil is independently activated by the electrical current passed therethrough. There is a projectile sized to be received within the bore of the barrel and having a circumferential armature at a tail end thereof, and a nose end. The projectile placed into the bore is fired by producing a traveling sequence of propulsive currents in the electrical excitation coils moving in a direction from the breech end toward the muzzle end of the barrel, so that a traveling propulsive magnetic field produced by the electrical excitation coils interacts with the armature of the projectile to propel the projectile in the direction from the breech end toward the muzzle end of the barrel. Simultaneously, a traveling sequence of field-nulling currents in the electrical excitation coils moves in the direction from the breech end toward the muzzle end of the barrel but closer to the muzzle end of the barrel than the traveling sequence of propulsive currents and spatially leading the traveling sequence of propulsive currents. The field-nulling currents are in a circumferential direction opposite to the propulsive currents, thereby at least partially nulling the traveling propulsive magnetic field at the nose end of the projectile.

    Abstract: An improved imaging system. The inventive imaging system (10) is adapted to transmit a plurality of first radar signals at millimeter wave frequencies at an area including an object along with background clutter. The return signals are processed to provide a three dimensional image for applications demanding visibility through fog, haze, smoke and other obscurants. Such applications include enhanced vision for helicopters, ships, buses, trucks, traffic observation stations for an intelligent highway or security cameras for plants and military installations. In a guidance system application, for example, the inventive system would include an electronically scanning antenna (12) to provide range and amplitude signals representative of a target area. The range and amplitude signals (18, 20) are compared to stored signals (26, 30) to create the three dimensional image. The stored signals are selected for comparison based on the dive angle of the missile (28, 32). The three dimensional image is then processed (22, 24, 34, 36, 38, 40) to derive guidance commands for the missile.

    Abstract: A precision-guided hypersonic projectile weapon system. The inventive system includes a first subsystem for determining a target location and providing data with respect thereto. A second subsystem calculates trajectory to the target based on the data. The projectile is then launched and guided in flight along the trajectory to the target. In the illustrative application, the projectile is a tungsten rod and the first subsystem includes a forward-looking infrared imaging system and a laser range finder. The second subsystem includes a fire control system. The fire control system includes an optional inertial measurement unit and predicts target location. The projectile is mounted in a missile launched from a platform such as a vehicle. After an initial burn, the missile launches the projectile while in flight to the target. The missile is implemented with a rocket with a guidance system and a propulsion system. In accordance with the present teachings, the guidance system includes a transceiver system mounted on the projectile. The transceiver system includes a low-power continuous wave, millimeter wavelength wave emitter. A system is included at the launch platform for communicating with the projectile. The platform system sends a blinking command to the projectile and measures the round trip delay thereof to ascertain the range of the projectile. Velocity is determined by conventional Doppler techniques or differentiation. Azimuth and elevation are then determined by a monopulse antenna on the launch platform. As a consequence, the platform ascertains the location of the projectile and the impact point thereof. The platform generates a command to the projectile which is received by the projectile and used to actuate control surfaces to adjust the trajectory and impact point thereof as necessary.

    Abstract: A missile guidance system designed to operate on GPS signals in an anti-jamming environment. The inventive system includes first, second and third airborne vehicles (20). A GPS receiver (24) is mounted on each of the three vehicles (20) to receive signals transmitted from spaceborne satellites (14). Each vehicle (20) acts as a pseudo-satellite or ‘pseudolite’. The received GPS signals are processed by a processor (26) to provide a first intermediate signal indicating the position of the vehicle (20). This signal is retransmitted from each vehicle and received by a GPS receiver mounted on a missile. The received intermediate signal is processed on the missile to provide an output signal indicating the position thereof. The pseudolites would be airborne in the vicinity of a target area. Because the pseudolites are relatively close to the targets compared to a satellite in high altitude orbit and because the pseudolites would be able to transmit a kilowatt or more power, the signal strength may be improved significantly. To succeed as a jammer, a jammer, successful against GPS satellites, would need considerably more power to succeed against aircraft carried pseudolites. The pseudolite system delivers GPS signals into the target area 40-70 dB stronger than signals coming directly from GPS satellites. By timing the signals for 100% time coverage, enemy C/A code receivers will be jammed because they are limited to a J/S capability of 30 dB.

    Abstract: A bomb damage assessment system that is carried by a weapon and released to provide imagery of a bombed area before and after bomb delivery. The system comprises a glider that is releasably secured to the weapon that includes tracking and guidance electronics for programmably controlling the flight thereof. An imaging system is disposed in the front end of the glider and a deployable ballute is disposed at the rear end thereof. A data link is provided for transmitting images to a command center for review. The system provides imagery of a target area before, during and after weapon impact. Television or infrared cameras may be used for day or night missions. As a target area is approached, the glider is released, is decelerated by the ballute, wings are unfolded, and the ballute is released, resulting in an aerodynamic vehicle that flies much slower than the weapon. The imaging system tracks the weapon to impact. The explosion of the weapon produces a hot spot that is tracked by the imaging system. The hot spot is tracked until a preselected depression angle is reached. The glider banks until the hot spot is at a predetermined angle relative to the centerline thereof. This results in a spiral glide path around the hot spot so that the target area is viewed from all aspects. The spiral path also results in a monotonically decreasing range to the hot spot. The glider may employ a GPS receiver, and the target location in GPS coordinates may be entered into the guidance and control system. The glider may be programmed to fly along a specific path or geometric surface in GPS coordinates toward the target. Using a fixed field of view imaging system, a large amount of background is seen from long range and better linear resolution is obtained at short range until the glider descends to the ground. Bomb damage assessment may be performed at the command center within minutes of weapon impact.
