摘要： Radio frequency motion sensors may be configured for operation in a common vicinity so as to reduce interference. In some versions, interference may be reduced by timing and/or frequency synchronization. In some versions, a master radio frequency motion sensor may transmit a first radio frequency (RF) signal. A slave radio frequency motion sensor may determine a second radio frequency signal which minimizes interference with the first RF frequency. In some versions, interference may be reduced with additional transmission adjustments such as pulse width reduction or frequency and/or timing dithering differences. In some versions, apparatus may be configured with multiple sensors in a configuration to emit the radio frequency signals in different directions to mitigate interference between emitted pulses from the radio frequency motion sensors.

摘要： A narrowband AJ signaling system includes an AJ processor placed between a high precision analog-to-digital (ADC) converter and a narrowband digital receiver. In another example, the AJ processor is placed between the high precision ADC and a digital-to-analog converter (DAC). The AJ processor of either example may suppress the jammer power down to the level of the noise floor of the system.

摘要： One or more defined countermeasures are selected from a countermeasure library, populated with parameters, and applied against an unknown, ambiguous, or unresponsive imminent radar threat based on an analysis of a hostile RF waveform emitted by the radar threat. The analysis can include comparing static and/or dynamic features of the hostile RF waveform with features of known hostile RF waveforms. A parameter set associated with the selected defined countermeasure in the countermeasure library can be selected. Waveform features can be categorized and sub-categorized for comparison with the known hostile waveforms. A plurality of features can be detected and compared. The analysis can include correlating behavior patterns of a plurality of hostile RF waveforms emitted by the radar threat. A cognitive intelligence trained using a threat database and library of corresponding countermeasures can analyze the hostile RF waveform, select the defined countermeasure, and/or select or generate the parameters.

摘要： An apparatus for generating a jamming signal comprises a signal receiving unit configured to receive an external pulse signal, an amplitude signal generating unit configured to generate an amplified signal by amplifying the pulse signal, a noise signal generating unit configured to generate a noise signal having a bandwidth including a bandwidth of the pulse signal, a control unit configured to control the amplified signal generating unit and the noise signal generating unit such that a signal-to-noise ratio of the amplified signal and the noise signal to be received by an apparatus that has transmitted the pulse signal becomes constant based on characteristics of the pulse signal and a signal radiating unit configured to radiate the amplified signal and the noise signal.

摘要： The present disclosure relates to exemplary embodiments of radar systems for providing increased robustness against radar interference transmissions and methods for controlling such radar systems. The radar system comprises at least one radar antenna configured at least for receiving a radar signal, a radar signal dividing means, a first receiver device and a second receiver device. The first receiver device is configured for monitoring a first frequency range and the second receiver device is configured for monitoring a second frequency range, wherein the second frequency range is wider than the first frequency range and the first frequency range is a subset of the second frequency range. The second receiver device is configured for measuring interference levels within the second frequency range. The present disclosure further relates to exemplary embodiments of methods for controlling the radar system, wherein the methods refer to measuring interference levels within the second frequency range, analysing measured interference levels, determining favorable frequency channels within the second frequency range in respect to interference level and possibly changing operating frequency channel in respect to measured interference levels.

摘要： In a radar device mounted in a host vehicle, a radar transmitting unit transmits a radar signal; a light detection unit detects ON or OFF of a light of another vehicle in which the radar device is mounted; and a timing control unit sets a transmission timing of the radar signal and a light ON timing of a light of the host vehicle, the light ON timing is synchronized with the transmission timing on basis of detected ON or OFF of the light of the other vehicle. The set transmission timing is different from a transmission timing of a radar signal of the radar device mounted in the other vehicle.

摘要： Systems, devices, and methods efficiently calculate optimal flight paths for protected entities given terrain data, aircraft position, flight characteristics, and positions of known threat emitters. The systems and methods execute within the mission planning timeline, and the developed processes allow users to retrieve data from the calculations to effectively place an electronic attack platform at the right place and at the right time to be effective. The calculated optimal flight paths are displayed or otherwise visualized in the mission space. Electronic attack jamming capabilities are combined with projected threat emitter performance information in order to obtain optimal geometrical positioning of the electronic attack relative to the threat emitter. Threat emitter system characteristics are combined with electronic attack aircraft capabilities while simultaneously incorporating the position of the protected entity aircraft and rendered to assist the electronic attack aircrew in providing optimal electronic attack capabilities to protect one or more entities.
