摘要:
A portable countermeasure device is provided comprising one or more directional antennae, one or more disruption components and at least one activator. The portable countermeasure device further comprises a body having a dual-grip configuration, with the directional antennae are affixed to a removable plate on a front portion of the body. The one or more disruption components may be internally mounted within the device body. The dual-grip configuration allows an operator to use his body to steady and support the device while maintaining the antenna on target. The second grip is positioned adjacent the first grip, with the first grip angled toward the rear of the device and the second grip angled toward the front of the device. The portable countermeasure device is aimed at a specific drone, the activator is engaged, and disruptive signals are directed toward the drone, disrupting the control, navigation, and other signals to and from the drone.

The system and method of utilizing frequency waterfilling and implicit coordination to mitigate signal jamming in Link 16 systems. The system and method of utilizing frequency waterfilling for Link 16 includes updates to both software and firmware. The frequency waterfilling approach for Link 16 modifies the process by which data bits are allocated to hops based on an assessment of hops affected by jamming, thus avoiding portions of the spectrum occupied by a jammer.

A system for near field communications is provided. The system can include a near field generator configured to generate a near field detectable signal comprising information. The system can include a near field detector configured to receive the near field detectable signal and output the information. The system can include an Electro-Magnetic (EM) shield surrounding the near field generator to block EM radio frequency (RF) signals in the vicinity of the near field generator from interfering with operations of the near field generator. The EM shield does not prevent communication of the near field detectable signal between the near field generator and the near field detector. The EM shield can be configured to reduce magnetic field loss from eddy currents in the EM shield as the near field detectable signal passes through the EM shield.

Embodiments of a method and apparatus for assigning electromagnetic-spectrum (ES) jamming assets are generally described herein. In some embodiments, the method includes dividing an electronic warfare (EW) support area into a grid. The method may further include determining a vulnerability area (VA) of the entity based on planned route information of the entity within the EW support area. The VA may include portions of the grid. The method may further include assigning a first jamming asset to the VA based on a coverage capability of the first jamming asset. The coverage capability may include a number of contiguous portions of the grid.

A system is provided that has an ECM (electronic counter measures) system and a transponder monitor connected to or forming part of the ECM system. The system monitors for a transponder signal from a remote transponder. The system determines information, such as transponder location, based on the transponder signal and makes use of the information in the ECM system and/or the system extracts encoded information contained in the transponder signal, such as information about a transponder owner, such as status of consumables, medical status. The ECM system may have a reactive jammer that is used both for a reactive jamming function, and as the transponder monitor function.

A device and method for estimation of the transmission characteristics of a Radio Frequency system are provided. The device and method calculate a predicted receive power at a given location using a propagation and scenario model. Then a measured receive power at the given location is used to determine a correction value equal to the difference between the calculated and measured receive powers. The correction value and the propagation model are then used with a heuristic method to refine estimates of propagation and scenario parameters. The refined parameter set is used to produce a refined prediction of receive power, which is used to create a refined correction factor. The refined correction factor is used to determine predicted receive powers at a plurality of locations.

A device and method for estimating the operational effectiveness, status, and protection range of an electronic countermeasures system in real time or near real time are provided. The device and method calculate a predicted ECM power at a given location using a propagation and scenario model. Then a measured ECM power at the given location is used to determine a correction value equal to the difference between the calculated and measured ECM powers. The correction value and the propagation model are then used with a heuristic method to refine estimates of propagation and scenario parameters. The refined parameter set is used to produce a refined prediction of ECM power, which is used to create a refined correction factor. The refined correction factor is used to determine predicted ECM powers at a plurality of locations in an area around the device to determine a boundary of protection.
摘要:
An automatic system is provided for alerting ground personnel as to the existence of a threat to commercial aircraft in which the threat is determined by a classified system, but in which the local area network employed by the military missile warning is isolated from an unclassified local network coupled to the aircraft's transponder which transmits the threat existence and status to ground personnel. The barrier to transmitting classified information involves both filtering between the classified LAN and unclassified LAN, the use of only discrete signaling lines in the classified LAN isolated by opto-electronics to provide physical separation between the two local area networks, and communications formatting which precludes the transmission of classified information across the barrier between the classified local area network and the unclassified local area network.
