摘要： A programmable radio frequency (RF) memory system includes a receiver designed to receive an RF pulse, a memory, a waveform transform module, and a transmitter. The memory stores a digitized version of the RF pulse. The waveform transform module is designed to determine one or more characteristics of the digitized version of the RF pulse, and based on the determined one or more characteristics, transform the digitized version of the RF pulse into a transformed signal. The transformed signal has at least one characteristic that is different than the one or more characteristics. The transmitter is designed to transmit an analog equivalent of the transformed signal. The analog equivalent of the transformed signal and the received RF pulse are coherent.

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 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.

摘要： A method for communication includes generating a data transmission for transmission to a target receiver, and generating at least one jamming transmission having an amplitude that changes multiple times during the data transmission. The data transmission is transmitted to the target receiver using an antenna array, and the at least one jamming transmission is simultaneously transmitted using the antenna array.

摘要： A radio wave jamming system (1) comprises a plurality of radio transmitters (10) that are adapted to transmit respective jamming signals (11) including substantially the same frequency. The plurality of radio transmitters (10) are further adapted to temporally change at least one of the transmission phases of the jamming signals (11), which are to be transmitted from the plurality of radio transmitters (10), so as to temporally change the phase differences among the jamming signals (11) when the jamming signals (11) transmitted from the plurality of radio transmitters (10) arrive at a particular site (50). Thus, for example, a radio wave jamming system that can be constituted by small-output radio devices can be provided.

摘要： In examples, Radio Frequency Iterative Time-Reversal (RF-ITR) and singular value decomposition (SVD) are used by an array of nodes to characterize environment by identifying scatterer objects. The array may be ad hoc dynamic or stationary. The environment is cancelled from the RF-ITR by adjusting Time-Reversal (TR) prefilters, reducing illumination of the scatterer objects in the environment. This enables the RF-ITR process to focus on a moving target, which can then be sensed (discovered, identified, monitoring, tracked, and/or imaged). The moving target on which the RF-ITR process focuses may then be cancelled from the RF-ITR in the same way as the environment, allowing the RF-ITR to focus on another target. Multiple moving targets can thus be sensed. Defensive measures such as jamming may then be taken against the targets. ii The targets may be distinguished from the scatterer objects in the environment through differential, Doppler processing, and other classification techniques.

摘要翻译： 在示例中，射频迭代时间反转（RF-ITR）和奇异值分解（SVD）被节点阵列用于通过识别散射体对象来表征环境。 阵列可以是静态的或静态的。 RF-ITR通过调整时间反转（TR）预滤器来消除环境，从而减少了散射体对象在环境中的照射。 这使得RF-ITR过程能够集中在移动目标上，然后可以感测（发现，识别，监视，跟踪和/或成像）目标。 RF-ITR流程重点关注的移动目标可以以与环境相同的方式从RF-ITR中取消，从而允许RF-ITR集中在另一个目标上。 因此可以感测到多个移动目标。 然后可以采取防范措施，如干扰，对目标。 ii可以通过差分，多普勒处理和其他分类技术将目标与环境中的散射体物体区分开来。

摘要： Various embodiments provide an ability to analyze an audio input signal and generate a counter audio signal based, at least in part, on the audio input signal. In some cases, combining the audio input signal with the counter audio signal renders the audio input signal incoherent and/or unintelligible to accidental listeners and/or listeners to whom the audio input signal is not directed towards. Alternately or additionally, the counter signal can mask the audio input signal to the accidental listeners.

摘要： A wideband intelligent jamming control apparatus and method is provided, which efficiently control an unauthorized threat signal. The wideband intelligent jamming control apparatus includes a signal detection terminal for detecting and analyzing wideband frequency signals in real time, and transmitting a jamming command and jamming signal specification information if a corresponding wideband frequency signal is determined to be an unauthorized threat signal. A jamming terminal receives the jamming command and the jamming signal specification information, and generates and emits a jamming signal based on the jamming command and the jamming signal specification information. The signal detection terminal and the jamming terminal may be configured to be physically separated from each other and may be controlled on a network.
