    Abstract: The range of energy transmissions or bursts (e.g., the range of high power microwave (HPM) directed energy weapons) may be increased using multiple sources (e.g., multiple HPM sources). For instance, according to techniques described herein, the individual sources may be fired at precise times such that the electromagnetic pulses are efficiently generated by each source and accurately add waveform peaks on the target. One or more aspects of the described techniques achieve sub-nanosecond timing accuracy by placing an HPM source, ultra-stable clock, and a laser pulse detector on each HPM weapon platform. For instance, the array may be triggered by firing a laser pulse at the target from one platform. By timing the firing of each HPM source based upon when the reflected laser pulse arrives at each platform as measured by the clock, the HPM pulses may arrive on target more accurately (e.g., more simultaneously).

    Abstract: Features for in-flight recovery of an unmanned aerial vehicle (UAV). A towline may be deployed by a host aircraft in-flight to recover an in-flight target UAV. The towline or portion thereof may be oriented nearly vertical. The towline may have a fitting thereon. A capture mechanism on the target UAV may have one or more deployable flaps that engage with the near vertical towline and fitting. The flaps may stow to secure the target aircraft to the towline and fitting. The host aircraft may then retract the towline to pull in the target UAV to the host aircraft using a hoist system having a winch. A latching system located in a pylon of the host aircraft, which may be under a wing, may have a towline connector that engages with and secures the target UAV. The host aircraft may have multiple hoist systems for deployment and/or recovery of multiple target UAV's.

    Abstract: A radome structure for a multilayered broadband radome structure is described. The radome structure may include a central core layer comprising a first dielectric constant, an interior intermediate core layer adjacent to an interior side of the central core layer, comprising a second dielectric constant less than the first dielectric constant, an exterior intermediate core layer adjacent to an exterior side of the central core layer, comprising a third dielectric constant less than the first dielectric constant, and an interior outside core layer adjacent to an interior side of the interior intermediate core layer, comprising a fourth dielectric constant less than the second dielectric constant. In some examples of the radome structure described above may further include an exterior outside core layer adjacent to an exterior side of the exterior intermediate core layer, comprising a low dielectric constant.

    Abstract: Fuel isolation systems, apparatuses and methods are described. In some embodiments, a system comprises a fuel tank, a fuel pump, an engine, a firewall, a fuel line from the fuel tank to the engine, a connector coupled inline with the fuel line on a cold side of the fuel line, a valve coupled to the connector, an air feed line coupled to an air source and to the valve. In the event of an engine fire condition, a control unit outputs signaling to turn off the fuel pump and operate the valve to introduce air from the air source into the fuel line. The introduced air provides a siphon break in the fuel line such that the only fuel that can pass the firewall is the remaining fuel in the fuel line downstream of the connector and the introduced air.

    Abstract: Some embodiments provide enhanced resolution imaging systems comprising: a mounting; an electro-optical image capture system; an angular jitter sensor system; an illumination source system; and an image capture control circuit is configured to: receive ling of sight displacement sensor data; obtain, during the capture frame, an angular displacement of the image capture system and monitor when the detected angular displacement of the image capture system, based on the sensor data, is beyond an angular displacement threshold envelope; and activate exposure of the image capture system to illumination, during the capture frame, when the detected angular displacement of the image capture system is within the angular displacement threshold envelope, and control a level of exposure of the image capture system to illumination, during the capture frame, when the detected angular displacement is not within the angular displacement threshold envelope.

    Abstract: Disclosed are devices and methods for selecting, at an antenna reflector, electromagnetic waves with a certain polarization and frequency and rejecting electromagnetic waves with different polarizations and/or frequencies. In one aspect, a directional antenna includes a shaped reflector surface with a series of conforming layers attached to the surface. The layers include a reflecting layer that causes reflection of electromagnetic waves at a specific frequency and polarization. Underneath the reflecting layer is a frequency selective surface (FSS) layer that absorbs electromagnetic waves not at the specific frequency or polarization which pass through the reflecting layer. Underneath the absorbing layer is a conductive layer.
