    Abstract: Techniques are provided for jammer detection. A methodology implementing the techniques according to an embodiment includes estimating an angle of arrival of a jamming signal, the jamming signal included in a received signal, and generating a direction finding (DF) confidence indicator associated with the estimated angle of arrival. The method also includes extracting the jamming signal from the received signal. The method further includes correlating the extracted jamming signal with previously extracted jamming signals to generate a correlation score and using the correlation score as a uniqueness assessment of the extracted jamming signal. The method further includes identifying characteristics of the extracted jamming signal and generating a characterization confidence indicator. The method further includes demoting the extracted jamming signal to non-jammer status based on one or more of the DF confidence indicator, the uniqueness assessment, and the characterization confidence indicator.

    Abstract: A method, system, and computer readable medium for performing a generalized angle-based tracker for a target determines angle-based information from a target signal, and initializes a Stationary Surface Filter (SSF), a Moving Surface Filter (MSF), and a Pseudorange Kalman Filter (PKF) with the angle-based information. Next, the SSF and MSF are scored by the PKF. If the information is associated, then the SSF, MSF, and PKF are updated. It is determined if at least one plausible Constituent Kalman Filter (CKF) exists for the SSF and MSF. If at least one CKF exists for the SSF and no CKF exists for the MSF, then the target is stationary surface; if at least one CKF exists for the MSF and no CKF exists for the SSF, then the target is moving surface; if no CKF exists for both the SSF and the MSF, then the target is moving airborne.

    Abstract: An anomaly detection system is disclosed. In an embodiment, the anomaly detection system includes an anomaly detection module and a warning indicator module. The anomaly detection module includes one or more auto-encoders that receive sensor data from a plurality of sensors. Each of the one or more auto-encoders receives sensor data from at least three different sensors of the plurality of sensors. By receiving data output from at least three of the sensors, the auto-encoder can recognize expected inter-related patterns from the sensor output. The warning indicator module compares an output of a given auto-encoder of the plurality of auto-encoders to an input of the given auto-encoder to obtain an error value, and then compares that error value against an error threshold. In response to the error value exceeding the error threshold, the warning indicator module issues a warning signal associated with the sensor data received by the given auto-encoder.

    Abstract: A switch assembly and a method of effecting a battery to initiate. The switch assembly includes a support that is adapted to operably engage with a battery. The switch assembly also include a slide operably engaged with the support and moveable in a first direction relative to the support between a primed position and a released position. The switch assembly also includes a cover operably engaged with the support and enclosing the slide. The switch assembly also includes a firing pin mechanism operably engaged with the support, the slide, and the cover and moveable in a second direction relative to the slide and the support. In the switch assembly, the second direction of the firing pin mechanism is different than the first direction of the slide.
