摘要:
This application relates to a non-communication electronic warfare system design analysis system based on engineering modeling. In one aspect, the system includes a scenario unit transmitting a simulation threat signal corresponding to an input scenario and a threat signal simulator transmitting an actual threat signal. The system may also include an electronic warfare support receiving model unit allocating a jamming technique. The system may further include an electronic warfare support receiving analyzer allocating the jamming technique to the received actual threat signal and an electronic attack jamming model unit modelling a device for generating a simulation jamming signal. The system may further include an electronic attack jamming generator generating an actual jamming signal and a simulation situation demonstration controller analyzing performance by using the actual jamming signal and the actual threat signal.

A countermeasure method for directing a mobile tracking device away from an asset is provided. The countermeasure method includes directing the output of a continuous wave laser source at a seeker head of the mobile tracking device. The countermeasure method causes the generation of localized sources within the mobile tracking device and confuses the mobile tracking device as to the true location of the asset.

A wireless microwave interferer for destructing, disabling, or jamming a trigger of an improvised explosive device. The interferer includes a power source interface, a control and monitoring panel, a waveform generator, a modulated HV power supply, at least one microwave generator, a waveguide to co-ax transformer and combiner, one of an ellipsoidal antenna and a spiral antenna, and an antenna adjustment mechanism. The power source interface interfaces with a power source. The waveform generator is connected to the modulated HV power supply and to the control and monitoring panel. The control and monitoring panel is connected to the power source interface, the modulated HV power supply, and the antenna adjustment mechanism. The modulated HV power supply is connected to the at least one microwave generator. The at least one microwave generator is connected to the waveguide to co-ax transformer and combiner. The waveguide to co-ax transformer and combiner is connected to the one of the ellipsoidal antenna and the spiral antenna. The one of the ellipsoidal antenna and the spiral antenna is connected to the antenna adjustment mechanism.

Apparatuses forming portable identification cards and associated methods are described. A preferred apparatus includes an input device adapted for a consumer to enter authentication data, a memory for storing reference data, a processor configured to compare the authentication data entered by the consumer to the reference data stored in the memory to determine whether the authentication data entered by the consumer is valid authentication data, an indicator for informing a merchant when the processor has determined that the consumer has entered valid authentication data, and a power source adapted to supply power to the processor and the indicator. Other features are also disclosed.

An RFDE system includes an RFDE transmitter and at least one RFDE antenna. The RFDE transmitter and antenna direct high power electromagnetic energy towards a target sufficient to cause high energy damage or disruption of the target. The RFDE system further includes a targeting system for locating the target. The targeting system includes a radar transmitter and at least one radar antenna for transmitting and receiving electromagnetic energy to locate the target. The RFDE system also includes an antenna pointing system for aiming the at least one RFDE antenna at the target based on the location of the target as ascertained by the targeting system. Moreover, at least a portion of the radar transmitter or the at least one radar antenna is integrated within at least a portion of the RFDE transmitter or the at least one RFDE antenna.

Apparatus forming a portable charge, debit or similar identification card which can be read using a magnetic card reader and methods for securing information are described. The preferred apparatus includes a magnetic stripe for storing information, a jamming assembly configured to emit a jamming signal which temporarily renders at least a portion of the magnetic stripe unreadable when the card is swiped through the card reader without first entering correct authentication data, and a power source adapted to supply power to the jamming assembly. Other features are also disclosed.
摘要:
A laser transponder for disabling a laser-based speed monitor which is transmitting a monitor laser beam at a moving vehicle by transmitting a jamming laser beam to the laser-based speed monitor. The monitor laser beam is in the shape of a monitor signal that includes monitor pulse trains emitted at a first frequency, while the jamming laser beam is in the shape of a jamming signal that includes jamming pulse trains emitted at a second frequency.

Means and method for jamming IR radiation-seeking threat missiles comprising means for generating wavetrains of randomized pulses of radiation of the same wavelengths at which the threat missiles are operating. The apparatus consists generally of radiation-generating means, means for pulse-modulating the radiation-generating means or the radiation itself with a wavetrain of random or pseudo-random pulses, and means for directing the modulated radiation at a target.
