51. Defense Or Civil Radar – It’s A Matter Of Wave Propagation 4/11/2019

    This white paper discusses the design challenges faced and the solutions available for today’s radar needs, both for defense and civil applications.

52. Protecting The Sky: Signal Monitoring Of Radio Controlled Civilian UAVs And Possible Countermeasures 4/10/2019

    This white paper discusses the use, specifications, and impact of radio-controlled UAVs. UAVs intended for recreational use are increasingly being used for other purposes, including observing/disturbing public events, spying in protected areas, smuggling contraband into prisons, and more. 

53. 28 nm Analog-To-Digital Converters Enable Next-Generation Electronic Warfare Receiver Systems 4/3/2019

    This white paper focuses on how 28 nm ADC enable faster sample rates, wider analog input bandwidth, integrated digital functionality, and new receiver architectures, all while reducing power consumption and overall size.

54. Resource Scaling For Antenna Placement Modeling On A SAAB JAS-39 Gripen Aircraft 2/28/2019

    This white paper demonstrates how resource requirements scale for the computational electromagnetic modeling of a modern fighter aircraft when the frequency increases. It also demonstrates how different simulation methods may be applied and how they scale relative to each other.

55. Development Techniques For Small Form Factor RF Signal Recorders 1/29/2019

    This paper describes the engineering considerations and design techniques used to develop a small form factor rugged recorder that can handle the extremely high data rates associated with very wide bandwidth RF signal recording, while focusing on military spec compliance, SWaP, and ease of use.

56. Hexadrone Systems Uses Fischer Connectors For Rugged Miniaturization And Modularity 1/24/2019

    Robotics and unmanned applications rely on connectivity solutions that combine miniaturization with ruggedness for high performance. Fischer Connectors translates these requirements into innovative custom solutions with the Fischer MiniMax Series connectors.

57. Countering Small Unmanned Aircraft Systems (sUAS) 1/10/2019

    The small Unmanned Aircraft Systems (sUAS) market has experienced exponential growth with the advent of brushless electric motors and high energy density lithium batteries. However, this accessibility also increases potential for weapon platforms, privacy violations, and interference.

58. Preparing For The SWARM 12/5/2018

    Commercial and government programs aim to employ “swarms” of UAV’s in domestic and overseas operations. These swarms can be controlled through autonomous UAV synchronization and formation flight, requiring minimal sensor operators.

59. Selecting Microstrip Filters To Deliver Small Size At High Frequencies 11/19/2018

    When selecting a filter implementation, one common factor across all frequencies is optimizing the size of the filter to the application and its required performance. This article discusses the benefits of microstrip filters to deliver higher frequencies in mmWave applications at smaller component sizes.

60. Cobot, The Collaborative Robot – Get Ready For Industry 4.0 10/30/2018

    Altair’s new cobot – a complex machine interacting with a human operator – is an example of a new successful design method with the use of simulation tools in industry 4.0. When creating complex products such as this, engineers must consider the entire mechatronics system, including structure, sensors, actuators with dynamic controls, electromagnetic compatibility. They must also interconnect machines for more flexibility, and increase productivity optimizing the maintenance process. This article discusses the design process for a cobot virtual demonstrator and how Altair’s HyperWorks was used in the process.
