  • 32571.以改进传感器集成(ISI)系统为目标的赤土采收,EUGS和光标

    [计算机、通信和其他电子设备制造业] [2014-05-21]

    The Improved Sensor Integration (ISI) project is an effort to cross- cue various force protection and persistent surveillance systems from unattended ground sensor systems and other data sources. The ISI systems communicate primarily through cursor on target messages. The Terra Harvest controller architecture was adopted to integrate the Applied Research Associates Expendable Unattended Ground Sensor (EUGS) system into the ISI project and provides a potential entry point for other types of unattended sensors. This report describes the architecture used to integrate EUGS into the ISI system by way of Terra Harvest and Cursor on Target, and discusses some of the issues and solutions that were identified during the integration.

  • 32573.无人值守地面传感器应用于人类的社会文化行为监测

    [计算机、通信和其他电子设备制造业] [2014-05-21]

    Textron Defense Systems has developed a wide range of unattended ground sensor (UGS) systems for the military and border patrol. These include T-UGS (Tactical UGS), U-UGS (Urban UGS), and most recently the new MicroObserver? multimodal UGS system. MicroObserver? is characterized by its best-in-class covertness, ease of deployment, negligible false alarm rate, and extremely long battery life (2+ years), yet with very low total cost of ownership. It uses advanced tracking and imaging algorithms to provide detection, classification and identification of both personnel and vehicles, and is proven in operational use to deliver reliable actionable intelligence to remote operators.

  • 32575.3-D成像激光雷达的Flash技术的直升机飞行安全试验,自主和精确的行星着陆

    [计算机、通信和其他电子设备制造业] [2014-05-21]

    Two flash lidars, integrated from a number of cutting-edge components from industry and NASA, are lab characterized and flight tested for determination of maximum operational range under the Autonomous Landing and Hazard Avoidance Technology (ALHAT) project (in its fourth development and field test cycle) which is seeking to develop a guidance, navigation, and control (GN&C) and sensing system based on lidar technology capable of enabling safe, precise crewed or robotic landings in challenging terrain on planetary bodies under any ambient lighting conditions. The flash lidars incorporate pioneering 3-D imaging cameras based on Indium-Gallium-Arsenide Avalanche Photo Diode (InGaAs APD) and novel micro-electronic technology for a 128 x 128 pixel array operating at 30 Hz, high pulse-energy 1.06 micrometer Nd:YAG lasers, and high performance transmitter and receiver fixed and zoom optics. The two flash lidars are characterized on the NASA-Langley Research Center (LaRC) Sensor Test Range, integrated with other portions of the ALHAT GN&C system from partner organizations into an instrument pod at NASA-JPL, integrated onto an Erickson Aircrane Helicopter at NASA-Dryden, and flight tested at the Edwards AFB Rogers dry lakebed over a field of human-made geometric hazards during the summer of 2010. Results show that the maximum operational range goal of 1 km is met and exceeded up to a value of 1.2 km. In addition, calibrated 3-D images of several hazards are acquired in real-time for later reconstruction into Digital Elevation Maps (DEM's).

  • 32576.仪器系统的信号调节电路的设计

    [计算机、通信和其他电子设备制造业] [2014-05-21]

    This report details the current progress in the design, implementation, and validation of the signal conditioning circuitry used in a measurement instrumentation system. The purpose of this text is to document the current progress of a particular design in signal conditioning circuitry in an instrumentation system. The input of the signal conditioning circuitry comes from a piezoresistive transducer and the output will be fed to a 250 ksps, 12-bit analog-to-digital converter (ADC) with an input range of 0-5 V. It is assumed that the maximum differential voltage amplitude input from the sensor is 20 mV with an unknown, but presumably high, sensor bandwidth. This text focuses on a specific design; however, the theory is presented in such a way that this text can be used as a basis for future designs.

  • 32579.检测水和冰对桥梁结构的交流阻抗和介电弛豫谱,第三及第四期:现场测试和细化新型水和桥面冰传感器系统

    [计算机、通信和其他电子设备制造业] [2014-05-21]

    During Phases III and IV of this project it was determined that the physical attributes of the prototypes developed during the earlier work was inappropriate for bridge deck installations. Mn/DOT engineers required that they be planar and not require drainage through the deck. As RWIS platforms had been widely deployed on decks throughout the state, we decided to adhere to the RWIS geometric format. This necessitated a significant re-engineering of the sensor hardware before installation and testing at remote bridge sites could proceed. To that end extensive development of a robust sensor meeting these requirements was developed and tested without compromise to the earlier performance results. In large part the maintenance of performance was achieved through a significant modification of the software to include Wavelet analysis of the raw data in the determination of surface state of the sensor platform (ice vs air vs water vs electrolyte present on the sensing electrode structure). The combined regression results for raw TDR responses treated by three analysis procedures are shown to give rise to very reliable results. Unfortunately, remote field testing of sensors installed on bridge decks was not accomplished.

  • 32580.高光谱成像仪使用MOBY和AERONET-OC数据对沿海海洋(HICO)进行替代定标

    [计算机、通信和其他电子设备制造业] [2014-05-21]

    The Hyperspectral Imager for Coastal Oceans (HICO) was constructed and is managed by the US Naval Research Laboratory (NRL). Pre-launch calibration, and therefore sensor measurement accuracy, of satellite sensors can be affected by launch vibrations, temperature fluctuations, space radiation and other factors. Vicarious correction was applied to HICO imagery to improve measurement accuracy. Vicarious calibration applies a 'reverse' atmospheric correction where satellite-derived atmospheric factors are added to in situ normalized-water-leaving radiances to generate 'vicarious' top-of-atmosphere radiances that are used to compute gain and offset values. The gains and offsets are subsequently applied to satellite sensor top-of-atmosphere radiances to force closer agreement with in situ measurements. In situ data from the Marine Optical Buoy (MOBY) and from some of the NASA AErosol RObotic NET Ocean Color (AEONET-OC) platforms were used to provide in situ water measurements used to vicariously calibrate HICO data.
