摘要： A pulsed radar system uses phase noise compensation to reduce phase noise due to drift of the reference oscillator to enable detection of micro movements and particularly human motion such as walking, breathing or heartbeat. The noise level due to A/D sampling must be sufficiently low for the phase noise compensation to be effective. As this is currently beyond state-of-the-art for high bandwidth A/D converters used in traditional receiver design, the receiver is suitably reconfigured to use analog range gates and narrowband A/D sampling having sufficiently low noise level. As technology continues to improve, the phase compensation techniques may be directly applicable to the high bandwidth A/D samples in traditional receiver designs. Whether phase compensation is applied to traditional receiver designs or a receiver configured with analog range gates, the steps are essentially the same: data is processed to position a reference range bin (either an analog range gate or a particular time sample) on a stationary reference and the phase variation of that reference range bin is used to compensate the phase of target data in range bins (either an ensemble of range gates or other time samples) near the stationary reference. This effectively moves the radar system and particularly the reference oscillator to the stationary reference thereby greatly reducing oscillator drift and phase noise and decoupling the stand-off range from the level of phase noise.
摘要翻译：脉冲雷达系统使用相位噪声补偿来减少由于参考振荡器的漂移引起的相位噪声，以便能够检测微动，特别是人的运动，例如步行，呼吸或心跳。由于A / D采样引起的噪声电平必须足够低以使相位噪声补偿有效。由于目前在传统接收机设计中使用的高带宽A / D转换器目前已经超出了现有技术水平，接收机被适当地重新配置为使用具有足够低噪声电平的模拟量程门限和窄带A / D采样。随着技术的不断改进，相位补偿技术可以直接适用于传统接收机设计中的高带宽A / D采样。相位补偿是应用于传统接收机设计还是配置有模拟量程门限的接收机，步骤基本相同：将数据处理为将参考范围存储区（模拟量程门或特定时间采样）定位在固定参考点并且该参考范围bin的相位变化用于补偿在固定基准附近的范围仓（或范围门或其他时间样本的集合）中的目标数据的相位。这有效地将雷达系统，特别是参考振荡器移动到固定基准，从而大大降低了振荡器漂移和相位噪声，并将离散范围与相位噪声电平分离。

摘要： A recursive binary splitting and recombination procedure coupled with a specially tailored genetic algorithm provides a solution to the general binary minimization problem with much lower run times than other methods. A minor modification to the procedure solves a variant of the binary minimization problem using an alternate operator logic that is crucial to solving certain combinatorial geometry problems.

摘要： The descriptions of higher order complex geometry in CAD systems are fundamentally different from and seemingly incompatible with the surface based combinatorial geometry (SBCG) format for describing the same geometry in the context of general ray-tracing applications such as radiation transport. A computer implemented process translates the high order complex geometry embodied in CAD software to the SBCG format. The translation process is comprised of a set of lower-level algorithms that operate on two data sets which are commonly available from commercial CAD software systems. The first data set is a list of trimmed surfaces which make up a given part. These data are typically available from one of the standard geometry representations such as IGES, STEP, or ACIS, at least one of which is supported by each of the major CAD systems (e.g. ProEngineer). The second data set is nodal data: an appropriately dense grouping of point coordinates, designated as either inside or outside the part. These data may be obtained by discretizing solid geometry both within and external to the part of interest using standard FE tools (e.g. ProMechanica). The process translates these two data sets into a list of analytic surfaces and a well-posed zoning statement and then optimizes that statement.

摘要： A discrete event simulation (DES) and method of model development provide affordable, accurate, pre-validated, reusable and portable models and simulations that capture the complexity, interdependencies and stochastic nature of the operations and support (O&S) of weapons systems. A model of the O&S problem is created based on a service use profile (SUP) that describes a logical structure of delivery, maintenance, deployment, testing policy, infrastructure and logistics constraints. That model is translated into a DES, preferably using a “toolkit” including common attributes for the weapons and pre-validated common blocks and sub-models that define higher level functionality. The DES calculates a time-based prediction of weapons availability, maintenance activities, and spare parts stock over a life cycle of the weapons system.

摘要： A generalized Hough transform is used to acquire and track vehicular targets for missile guidance. This is accomplished by recognizing that most vehicles have silhouettes that may be described as a “rounded rectangle”. The position and shape of such rounded rectangles is described in terms of 5 parameters (xc, yc, a, b, θ) where xc, yc are the center coordinates, a,b are the major and minor axis and Θ is the orientation. The computation of a five dimensional Hough transform on an image including such a target will produce the five parameters that provide the “best fit” rounded rectangle to the target. These parameters are then passed to a missile tracker. This capability can be used to improve track gate handoff from the automatic target recognizer (ATR) to the missile tracker, changing aspect ratios of maneuvering targets, limited lock-on after launch (LOAL), aimpoint designation and fire control system to missile seeker handover.

The device includes a sense circuit to detect when a transient event occurs and one or more transistors configured to supply or sink current to the load. The system may include a second power regulator configured to respond to fast transient power demands.

摘要： A dual loop (PLL/DLL) data synchronization system and method for plesiochronous systems is provided. In particular, a system and method for dual loop data synchronization using a granular FIFO fill level indicator is provided. A dual loop data serializer includes a phase lock loop (PLL) and a delayed lock loop (DLL) configured with a phase shifter in the feedback path of the PLL. The dual loop serializer locks to the input of the DLL, which represents a fill level of a FIFO. A granular FIFO fill level indicator of the DLL provides input to the phase shifter to adjust the frequency of the PLL accordingly. Thus, the frequency of the data input rate can be controlled and a constant fill level of the FIFO can be maintained. A dual loop retimer includes a dual loop serializer (PLL/DLL) and a clock recovery DLL. The retimer resets the jitter budget to meet transmission requirements for an infinite number of repeater stages.

摘要： A band gap discontinuity is propagated across a Photonic Crystal (PC) to capture thermal energy in a region near the primary emission wavelength of the Planck spectral distribution and transfer that energy to a different spectral region where it is emitted. To extend the range of frequency shifting beyond the width of a single band gap, the intrinsic control parameters (e.g., lattice geometry factors, scattering element geometric factors, and variations in the index of refraction) are spatially varied across the PC to form a band gap gradient. Propagation of the band gap discontinuity, starting in the infrared wavelength region where the thermally generated electromagnetic energy is concentrated and propagating towards the long wavelength region, locally captures the thermal electromagnetic radiation, shifts it downwards in frequency, and pushes the lower-frequency thermal electromagnetic radiation on to the next region. The same principles apply to shift the frequency to shorter wavelengths. A PC-based power combining and waveguide structure can be constructed in the same or a surrounding structure to combine and guide the shifted radiation to an antenna or exit aperture.
