Abstract: An antenna system has N antenna units stacked on a mast. Each unit has elements for responding to, e.g., GPS signals, and a phasing network that produces mutually orthogonal primary and auxiliary pattern modes at corresponding mode ports of the unit. A number of power dividers are each associated with a different mode, and each divider has N input ports coupled to the associated mode port of a corresponding antenna unit. The power divider associated with the primary pattern mode produces a reference beam and an auxiliary beam, and remaining power dividers produce different auxiliary beams. All beams have approximately both a common phase center and a common group delay center. An adaptive processor combines the reference and selected auxiliary beams to obtain a composite antenna reception pattern in which nulls are inserted at certain angles to suppress interfering signals, without degrading authentic signals arriving at other angles.

Abstract: The system and method for clock synchronization, or calibration, for use in high speed asynchronous serial interfaces. The system and method is automatic, on-line, and occurs in real-time. The process of synchronization may also be started by a user. The calibration scheme is a form of adaptive filtering using 8B10B encoding. Once idle traffic is 8B10B encoded it becomes a stream of K28.5 characters. These characters are used to tune a clock frequency. The process stops, and two devices are synchronized, when the number of idle K28.5 traffic samples are uniformly approximately identical for any of two successive sample intervals.

Abstract: A multi-chip module hybrid integrated circuit (MCM-HIC) provides cold spare support to an apparatus comprising a plurality of ICs and/or other circuits that are not cold spare compliant. At least one core IC and at least one cold spare chiplet are installed on an interconnecting substrate having a plurality of power zones to which power can be applied and withdrawn as needed. When powered, the cold spare chiplets serve as mediators and interfaces between the non cold spare compliant circuits. When the cold spare chiplets are at least partly unpowered, they protect all interconnected circuits, and ensure that interconnected circuits that remain powered are not hindered by unpowered interconnected circuits. Cold spare chiplets can extend across boundaries between power zones. External circuits can be exclusively interfaced to a subset of the power zones. Separate power circuits within a power zone can be sequenced during application and withdrawal of power.

Abstract: An analog access circuit for characterizing chalcogenide memory cells is disclosed. The analog access circuit includes an analog access control module, an address and data control module, and an analog cell access and current monitoring module. The analog access control module selectively controls whether a normal memory access or an analog memory access should be performed on a specific chalcogenide memory cell. The address and data control module allows a normal memory access to the chalcogenide memory cell according to an input address. The analog cell access and current monitoring module performs an analog memory access to the chalcogenide memory cell according to the input address, and monitors a reference current from a sense amplifier associated with the chalcogenide memory cell.

Abstract: An algorithmic approaches that can be implemented in software/firmware/hardware that filters out stable PRI patterns detected within a system that is prosecuting against radar based transmissions are disclosed. The algorithms allow downstream computing assets to concentrate their limited resources on the more complex emitter PRI pattern types. Thus, a portion (e.g., stable signals) of the pulse deinterleave and PRI identification problem is solved without requiring the more computationally expensive processing. The disclosed algorithms can be employed, for example, in electronic support measures (ESM) systems, electronic intelligence (ELINT) systems, and/or a electronic countermeasures (ECM) systems. The algorithms employ linear detection, linear regression, or a combination of linear detection and linear regression, thereby providing a “dual voting” scheme that decreases the occurrence of false positives. Other algorithmic approaches can be used as well in a multi-voting scheme that considers PRI estimates from distinct analysis types.

Abstract: Pulse integration is utilized on board an optically guided missile or other ordinance device used as a part of a target designation system for extending the lock-on range of the missile by approximately 18%, when a double pulse laser is utilized to illuminate and designate the target. Pulse integration is accomplished with a recirculating delay unit which superimposes the first pulse on the second pulse, such that while the pulses add coherently, noise does not add in phase. The pulse integration technique therefore enhances the signal-to-noise ratio when the missile is at the outer limits of its operating range. When the missile is sufficiently close to the target, doublet decoding is actuated to offer countermeasure resistance. At this point, pulse integration may proceed in lieu of doublet decoding or may be dispensed with in view of the increased signal-to-noise ratio due to the close range of the missile to the target.

Abstract translation: 在使用双脉冲激光器照明并指定的情况下，用作目标指定系统的一部分的光导导弹或其他法令装置将脉冲积分用于将导弹的锁定范围延长大约18％ 目标。 脉冲积分是通过将第一脉冲叠加在第二脉冲上的再循环延迟单元完成的，使得当脉冲相加时，噪声不会相位增加。 因此，当导弹处于其工作范围的外部极限时，脉冲积分技术可提高信噪比。 当导弹足够靠近目标时，启动双重解码以提供对抗性。 此时，可以进行脉冲积分来代替双重解码，或者可以考虑到由于导弹到目标的近距离的增加的信噪比而被省去。
