Interoperable Communications Platform

NATO Special Forces Taps Mutualink for Global Cross Coalition Communications

NATO Special Operations Forces Headquarters (NSHQ) recently selected Mutualink as its official interoperable communications platform. Using Mutualink’s ruggedized Valence™ series platform, NATO SOF coalition partners will be equipped with advanced anywhere, anytime, interoperable communications and information sharing capability. This next generation capability securely links warfighters and command and control elements with each other as needed across different communications systems and allows them to share real time ISR, including files, maps, system views and full motion video (FMV) on the fly. For NATO SOF, quick reaction time and agile response capabilities are a must. Often first on the ground in challenging operational environments, harnessing collaborative multi-national information and intelligence sharing and seamless communications capability is critical.

Fastener Inserts

Fastener Inserts Designed for Lightweight Aerospace Materials Reduce Risks, Costs

Ongoing efforts to increase fuel efficiency, tactical mobility, and payload capacity in aerospace design have driven engineers to find numerous ways to reduce mass through the extensive use of lightweight materials such as composites, aluminum, and plastics. Use of these lightweight materials can create other issues, however, such as finding safe and reliable ways to fasten assemblies that provide complete assurance of joint integrity under the severe conditions of shock, vibration and thermal cycling common in aerospace applications.

Thermal-to-Visible Face Recognition

For nighttime surveillance, acquisition of visible light imagery is impractical due to the lack of illumination. Thermal imaging, which acquires mid-wave infrared or long-wave infrared radiation naturally emitted by the human body, can be utilized in low-light conditions to perform surveillance tasks. Identification of individuals captured by thermal imaging would significantly enhance nighttime intelligence gathering capabilities. However, government watch lists and databases almost exclusively contain visible-light face imagery of individuals of interest. Matching thermal face imagery to the existing databases therefore requires the development of across-modality face recognition algorithms and methods. Due to the large modality gap caused by the wavelength difference between visible and thermal radiation, thermal-to-visible face recognition is a challenging problem.

Target Detection and Classification Using Seismic and PIR Sensors

Unattended ground sensors (UGS) are widely used in industrial monitoring and military operations. Such UGS systems are usually lightweight devices that automatically monitor the local activities in-situ, and transfer target detection and classification reports to the processing center at a higher level of hierarchy. Commercially available UGS systems make use of multiple sensing modalities (e.g., acoustic, seismic, passive infrared, magnetic, electrostatic, and video). Efficacy of UGS systems is often limited by high false alarm rates because the onboard data processing algorithms may not be able to correctly discriminate different types of targets (e.g., humans from animals). For example, discriminating human footstep signals from other targets and noise sources is a challenging task, because the signal-to-noise ratio (SNR) of footsteps decreases rapidly with the distance between the sensor and the pedestrian.

Component Identification in Multi-Chemical Mixtures with Swept-Wavelength Resonant-Raman Spectroscopy

The utilization of ultraviolet resonance Raman spectroscopy for the detection and identification of chemical, biological, and nuclear hazards is of great interest due to the sensitivity and specificity afforded by this technique. Detection by means of optical probing is a fast, non-contact method that requires little to no sample preparation and can be performed remotely by an operator. In addition, this method is also well suited for use by an automated monitor or a mobile autonomous system, such as an in-situ environmental detector or a sensorequipped unmanned vehicle. In addition, this technique offers the ability for a single detector to identify multiple species of targets. However, for Raman detection to become practicable as a forensic tool, the method must demonstrate the ability to distinguish the target elements while operating in a complex environment.

Analysis of Mine Impulse Data Using Stereo-Digital Image Correlation

Improvised explosive devices (IEDs) and other traditional under-body blast weapons are a significant threat to military ground vehicle systems. Engineers and scientists attempting to analyze the effects of under-body blast events have an array of commercial and internally developed tools at their disposal, each with its own set of limitations. Finite element (FE) models offer the capability to evaluate the entire event sequence from the detonation of the buried explosive to the response of the occupant. However, FE models for full system-level mine events require significant time for input preparation, debugging, and computation.

XMC Module

Innovative Integration (Simi Valley, CA) has announced the new X6-250M that integrates digitizing with signal processing on a PMC/XMC IO module. The module has a powerful Xilinx Virtex 6 FPGA signal processing core, and high performance PCI Express/PCI host interface. Applications include software defined radio, RADAR receivers, and multi-channel data recorders. The X6-250M has eight simultaneously sampling A/D channels that sample at rates up to 310 MSPS (14-bit). The A/D have matched input delays and response and are supported by a programmable sample clock PLL and triggering that support multi-card synchronization for large scale systems. A Xilinx Virtex6 SX315T (LX240T and SX475T options) with 4 banks of 1GB DRAM provide a very high performance DSP core with over 2000 MACs (SX315T).
