Abstract: A simulated burst echo signal (artificial target), corresponding to a deld and conditioned version of an RF burst signal from an associated radar under test, is presented to the associated radar under test by coupling a portion of the RF burst signal into a shipboard sensor exerciser apparatus in which the present invention is employed to feed an attenuated facsimile of the RF burst signal into a phase-locked loop portion thereof. The phase-locked loop locks on to the attenuated facsimile of the RF burst signal and generates an error signal in response thereto. The error signal is then digitized and stored in an error storage unit portion where it is delayed for a predetermined time associated with the desired selected range of the artificial target.

Abstract: A device for rapidly measuring voltages by electro-optic or magneto-optic ans which exhibits a substantially linear response over much of its operating range. The device employs the Pockels effect in which the orientation of polarized light is altered in direct response to applied voltages. The response of the subject device is made substantially more linear by dividing the polarized light into two beams and retarding the phase of the second beam by one-quarter wavelength, attenuating its intensity by a factor of approximately four, and passing it through a second Pockels cell having a transducer constant of one half that of the first Pockels cell and then recombining, or superpositioning, the first and second beams of light, thus yielding a substantially linear response over much of the applied voltage range.

Abstract: An optical backplane for use in a high-speed, parallel signal processing tem. A plurality of circularly shaped optical conductors are arranged in a cylindrical topology. A plurality of printed circuit card connectors are disposed radially about the perimeter of the optical conductors. Each connector consists of a linear array of optical transceivers. The lens of each optical transceiver is mounted in a socket provided at the perimeter of each optical conductor. The optical transceivers convert electrical data information from printed circuit boards plugged into the circuit card connectors into optical data information. The optical data information propagates throughout the optical conductor thereby allowing data to be shared by the printed circuit boards.

Abstract: An inertia element within a projectile is displaced to a retracted position y acceleration of the projectile during launch to unblock displacement of a slider to an armed position in response to subsequent pressurization of a projectile flight motor. Safe separation timers are thereby enabled in response to proper launch to delay pressurization of the flight motor and powering of an explosive firing circuit through switches actuated by said displacement of the slider from a safe position to the armed position. The slider is held in its safe position by an electrically grounded shear wire that is ruptured in response to slider displacement thereby removing a power disabling shunt connection to the firing circuit.

Abstract: A microchannel plate device utilizing a semiconducting bulk material is cacterized by electron emissions of high output current density and efficiency. The channel passages in the plate device which are square in cross-section accommodates a larger open area ratio at the input and output plate surfaces. An extended range of high electron emission applications for the plate device is provided. Such applications may include a photocathode installation to which a modulation pulse input is applied under low voltages isolated from high post-accelerating voltages.

Abstract: A payout control arm is angularly displaceable about a brake shaft during yout of a cable from a storage reel in response to tensioning forces transmitted through the cable from a payout load, the cable being entrained about a pulley rotatably carried on the control arm in spaced relation to the brake shaft. Gearing drivingly connects the pulley to the brake shaft to stop payout and cause the cable to frictionally grip the pulley in response to brake engagement thereby preventing continued transmittal of tensioning forces to the reel.

Abstract: In response to an abort command, fragmentation of a propellant booster rot carried on a missile is limited by positioning of annular shaped charges at axially spaced locations on the outer shell of the booster rocket. Detonation of the charges thereby severs an intermediate section of the rocket from forward and aft sections which remain attached to the missile. The intermediate section is separated from the missile by such severing action to prevent further fragmenting forces from being imparted thereto.

Abstract: The conventional missile warhead is replaced by a dual wall composite franting warhead. This design consists of two concentric composite shells which sandwich a layer of fragmentation material. All missile structural loads are carried by the shells. The warhead is connected to the rest of the missile through end joints rigidly attached to the shells.

Abstract: A method for steering the gain of a multiple antenna Global Positioning System (GPS) receiver toward a plurality of a GPS satellites simultaneously is provided. The GPS signals of a known wavelength are processed digitally for a particular instant in time. A range difference or propagation delay between each antenna for GPS signals received from each satellite is first resolved. The range difference consists of a fractional wavelength difference and an integer wavelength difference. The fractional wavelength difference is determined by each antenna's tracking loop. The integer wavelength difference is based upon the known wavelength and separation between each antenna with respect to each satellite position. The range difference is then used to digitally delay the GPS signals at each antenna with respect to a reference antenna. The signal at the reference antenna is then summed with the digitally delayed signals to generate a composite antenna gain.

Abstract: The Airborne Infrared Transmissometer measures the infrared transmission between a test target aircraft and a detection system. A transmitter is attached to an aircraft and emits a calibrated infrared beam. A ground-based, shipborne, or airborne receiver measures the transmitted signals in the exact same path between the target aircraft and the detection system. Data recording equipment can be attached to both the transmitter and receiver to measure the associated outputs.
