Electronic System Design for Aerospace and Defense Webinar Series

Even in the age of fast and accurate EM simulation solutions, developing complex passive microwave components remains a challenging task. A novel hybrid solver solution is now available to address this design challenge and significantly shorten the development cycle for RF components. Offering a significant advantage over general solvers solely relying on 3D-FEM, this webinar will cover the rapid synthesis and optimization of such components using typical filter and horn antenna design examples.

The design of novel antennas and analysis of installed antennae performance on large platforms demands a highly scalable electromagnetics software solution powered by high-performance computing (HPC) infrastructure. As a global leader in electromagnetics and HPC technologies, Altair uniquely provides antennae and RF designers with powerful electromagnetics solutions to rapidly design and evaluate antennae installed performance. This webinar will cover specialized electromagnetics solutions differentiated by a) intuitive, guided workflows to accelerate antennae design and development, (b) seamless integration with private and cloud HPC resources for high-fidelity analysis of large structures, (c) unsurpassed results accuracy, and (d) ability to assess antennae(s) performance within multiple operating environment scenarios.             

Platforms like frigates, fighter aircraft and armored vehicles tend to contain many transmitting and receiving antennas for a variety of electronic systems such as communication systems (including SATCOM), radar, positioning systems, and more. Even though these systems may operate on different frequencies, due to their proximity they may interfere. To analyze for co-site interference using electromagnetics simulation solutions requires (a) accurate determination of the coupling between antennas over a broad frequency range, even if platforms are complicated, and no direct line of sight may exist, and (b) evaluation of the impact of non-linear electronic effects including harmonics, intermodulation, IF breakthrough, image frequency, Tx and Rx spectra, and receiver blocking. Altair’s full system solution for analysis of co-site interference will be presented in this webinar, along with a practical example where an interference problem is identified and eliminated.

A radome is a structural enclosure that protects antennas and electronics from harsh weather and environmental factors without degrading electromagnetic signals to the radar. It is designed to have minimal impact on the electrical performance of the antenna and to withstand structural and wind loading performance requirements. They are used across multiple industries, including aerospace, defense, electronics and telecommunications. Radomes, especially those containing multiple layers and curved FSS elements, are complex and the modelling and simulation of these systems can commonly take days and even weeks to complete. Altair’s streamlined radome simulation solution reduces this time to minutes. This webinar will overview Altair’s radome simulation solution and its application to design a radome system.

Innovation and digitization are key factors when designing advanced detection systems, autonomous vehicles and stealth technology, where electromagnetic simulation has become essential. In this webinar we will cover central concepts important to Radar Cross Section (RCS) and scattering calculations. This will include the exploration of various applications, highlighting some of the newest capabilities helping customers to solve challenging problems leveraging established and industry-leading solutions.

New technologies such as 5G, V2V-communication, e-mobility and IoT increase the number of electromagnetic field sources in the environment. When designing such electronic systems, compliance with electromagnetic radiation hazard standards (e.g., ICNIRP 2020) must be ensured. This webinar will discuss the hazards of electromagnetic radiation to personnel, ordnance, and fuel and how this can be mitigated through numerical field calculations with Altair technology. Defense, automotive and telecommunications case histories will be presented.

Using simulation to predict, analyze, optimize, and plan the coverage given by radio and radar systems is key to reduce development and planning times together with costs. Also, in some cases this is the only feasible approach to identify and fix communication issues.  This webinar will overview simulation strategies for propagation analysis in complex environments, including among others large-scale terrain, cities, or buildings with interior detail. Additionally, the effects of interference and jamming will be covered and how the frequency allocation for a system with many transmitters can be optimized automatically.
