Light Combat Tactical All-Terrain Vehicle

Oshkosh Defense, a division of Oshkosh Corporation, has unveiled its Light Combat Tactical All-Terrain Vehicle (L-ATV) utility variant for the Joint Light Tactical Vehicle (JLTV) program. The L-ATV utility variant fulfills the JLTV requirement for a two-seat cargo vehicle, while the L-ATV base variant meets the requirement for a 4-seat multipurpose vehicle. Both Oshkosh L-ATV variants leverage a common crew protection system, advanced automotive systems, and the patented Oshkosh TAK-4i™ intelligent independent suspension system to deliver a superior level of protection and off-road performance in a light vehicle.

Modeling and Simulation Techniques for Unmanned Vehicle Systems

Unmanned Autonomous Vehicle (UAV) systems have become possible in recent history thanks primarily to the effects of Moore’s Law — the doubling of processing power every 18 months. This trend, coupled with improvements in sensors and actuators, has enabled the advanced signal and data processing necessary to control UAVs. However, the complexity of UAV systems has taxed traditional design workflows, and revealed numerous challenges such as shorter design cycles, greater performance and reliability demands, and cost constraints.

An Improved SDR FPGA Verification Methodology for Emerging OFDMA Waveforms

The rapid evolution of commercial technologies such as Long Term Evolution (LTE) is becoming more attractive for Software-Defined Radio (SDR) and public safety applications [1,2]. They have the potential to support high data throughput applications with scalable subcarriers and the use of multiple antenna techniques such as Multiple-Input Multiple- Output (MIMO) technology.

Simulation Optimizes Safety and Performance When Integrating an Antenna Onto a Platform

Successful integration of an antenna onto a vehicle platform poses many challenges. Vehicle features impact antenna performance by blocking, reflecting, or reradiating energy, and co-site interference can impair the effectiveness of multiantenna configurations. Platform motion and environmental factors such as terrain and buildings may reduce system effectiveness in actual operational conditions. Furthermore, radiation hazards may pose risks to nearby personnel. Modeling and simulation provides a powerful tool to aid in understanding these issues and developing solutions.

Laser Polarimeter Classifies Remote Material

Advanced Optical Technologies, Inc. (AOT) has been awarded a Phase 2 SBIR contract to develop a next-generation laser polarimeter for the US Army RDECOM CERDEC Night Vision and Electronic Sensors Directorate (NVESD), traditionally known as the US Army Night-Vision Labs. The polarimeter will implement AOT’s polarization-components techniques (PCT), which apply machine-learning algorithms to polarimeter data for remote material classification.
