A combination conductor-antenna apparatus is provided comprising a surface that defines a passage for use as a receptor for a second conductor and for use as a waveguide. The surface is at least partially formed of an electrically conductive material, thus allowing the apparatus to serve as a medium by which an electrical signal can be transferred from a second conductor. Disposed within the passage is a pickup element for sensing and/or injecting electromagnetic energy in the passage, thus allowing the apparatus to serve as a medium for wireless communications.

Combination conductor-antenna

A method and apparatus for determining the position of a target are disclosed. The method includes collecting onboard the platform a first set optical radiation in a first bandwidth and a second set of optical radiation in a second bandwidth reflected from a field of view; and determining the position of the target from the difference between the detected first and second sets of optical radiation. The apparatus includes a pair of detection channels a pair of detection channels, each of which further includes at least three optical channels, each detection channel capable of collecting onboard the platform a first set optical radiation in a first bandwidth and a second set of optical radiation in a second bandwidth, respectively, reflected from a field of view. The apparatus further includes a plurality of electronics capable of determining the position of the target from the difference between the detected first and second sets of optical radiation.

Multi-spectral direction finding sensor having plural detection channels capable of collecting plural sets of optical radiation with different bandwidths

A method and apparatus for finding a relative direction to, a radial speed of, and a distance to a target is described. A laser source illuminates the target and the Doppler shifted return beam is incident upon a window system at an angle and is transmitted therethrough. The magnitude of the transmitted Doppler shifted beam decreases due to Fresnel transmittance. Opposing photomixers then detect this transmitted Doppler shifted beam, thereby creating a pair of detection signals that are mixed with a local oscillator signal. The mixing process creates Doppler frequency signals that are subsequently processed to determine the radial speed of the target. Due to the Doppler frequency component of the signals, objects in the same direction, but moving at different radial speeds, can be discriminated, as the relative direction processing occurs after the Doppler processing.

A fin assembly includes a fin base, a fin tip rotatably connected with the fin base, and means for selectively locking the fin tip in a chosen configuration. A vehicle includes a body defining a cavity therein and defining an opening through a wall thereof, a fin control mechanism disposed within the cavity, and a fin base having an axle extending through the opening and engaged with the fin control mechanism. The vehicle further comprises a fin tip rotatably connected with the fin base, and means for selectively locking the fin tip in a chosen configuration. A method for configuring a fin assembly on a vehicle includes providing a fin tip rotatably connected with a fin base being operably coupled with the vehicle and selectively locking the fin tip in a first position relative to the fin base.

A method and apparatus for finding a relative direction of received radiation is described. The received radiation is incident upon a window system at an angle and is transmitted therethrough. The magnitude of the transmitted radiation decreases as a continuous function of increasing angle of incidence, known as Fresnel transmittance. Opposing radiation detectors then detect this transmitted radiation, thereby creating a pair of detection signals, By dividing the difference of the detection signals by the sum of the detection signals, a processor generates a beta angle error curve and finds the relative direction of the radiation. Based upon this beta angle error curve, the processor generates an appropriate error correction signal for guiding an object based upon the relative direction of the received radiation. The method and apparatus are readily applicable to guiding munitions using a laser monopulse to designate a target.

Non-coherent fresnel direction finding method and apparatus

An obstacle avoidance system, apparatus, and method is described suitable for use on autonomously guided or man-in-the-loop guided vehicles such as aircraft, missiles, cars, and other types of vehicles. The system provides guidance instructions in the situation where the vehicle encounters an obstacle either directly or indirectly in its path while traveling to a desired destination or where vehicles are traveling in formation. The system can be applied not only to obstacle avoidance but also to trajectory shaping by defining obstacles, operational boundaries and/or threats which influence the trajectory of the vehicle.

An apparatus for controlling a trajectory of a projectile includes a planetary drive train, a yaw drive assembly engaged with the planetary drive train, and a pitch drive assembly engaged with the planetary drive train. The apparatus further includes a plurality of fin assemblies linked with the planetary drive train such that, as the planetary drive train is actuated by at least one of the yaw drive assembly and the pitch drive assembly, corresponding displacements are produced in the plurality of fin assemblies.

The invention, in one embodiment, is an apparatus for controlling the roll, pitch, and yaw attitudes of an air or sea vehicle. The apparatus includes an actuator including an actuation plane and an actuation mechanism, capable of displacing the actuation plane at three points; at least three non-propulsive fins; and a linkage between the actuator and each one of the fins, the linkage communicating the actuation plane's displacement to the respective one of the fins.
