Extended Reality/Cross Reality (XR), whose use cases have expanded from the world of gaming, keeps growing and evolving while taking in diverse technologies. Its use cases have been spreading in business in recent years, with new applications developed for such areas as simulation, training, learning, and collaboration.

Operating within the 8.0–12.0 GHz frequency range, X-Band radar systems have proved vital across various industries, including meteorology, air traffic control, defense, and maritime services. Their exceptional resolution and accuracy make them indispensable in our technology-driven world.

Today’s Multifunction Active Electronically Scanned Array (AESA) systems are engineered and manufactured to simultaneously perform different operations, such as radar, electronic warfare (EW), and communications functions. One of the most critical elements of digitally reprogrammable multifunction AESA systems are the fixed-frequency sources.

Electromagnetic simulation time and memory are dependent upon the electrical size of the model being simulated. In this paper, analysis between simulation runtime and memory between Altair Feko’s full wave/asymptotic solvers and parallel processes is performed using aircraft models provided in UT Austin’s RCS Benchmark Suite.

This article serves as an introduction to frequency modulated continuous wave (FMCW) radar generation within the 24 GHz ISM band. This includes the major building blocks required for this type of radar system such as ramp generation, transmit and receive stages, downconversion, and sampling.

Precision quartz crystals must operate reliably for many years under sometimes adverse conditions including large ambient temperature variations and exposure to moisture and other environmental contaminants.

The 21st-century battlefield evolution emphasizes advanced military systems like radar and ECM, demanding fast-paced, flexible, and cost-effective design strategies. Integrating high-performance testing instruments, dedicated software, and comprehensive support ensures optimal operation of these systems, meeting the rigorous standards and varied environments specified by the DoD.

This white paper examines the contrasts between traditional line of sight (LoS) radar and over-the-horizon (OTH) HF radar, driven by emerging threats like hypersonic missiles. It delves into HF propagation principles, interference sources, and operational OTH radar like ROTHR and JORN, while also addressing challenges in research, development, testing, and evaluation.

Although Silicon-on-Insulator (SOI) MMIC switches can achieve fast switching, wide bandwidth and high frequency and power, most come at high cost. GaAs MMIC switch designs achieve comparable performance at considerably lower cost with distinct advantages. Read why Mini-Circuits’ GaAs MMIC technology switches afford a compelling alternative to comparable SOI models.
