Designing and Optimizing an Inmarsat RF Front End Using an RF Transceiver With Digital Pre-Distortion

Radios can be brought to market quickly by designing market specific RF fronts ends for use with multi-market transceivers that cover a frequency range from 30 MHz to 6 GHz. We will be showing how to develop an Troposcatter (4.4-5 GHz) transceiver using Wolfspeed PA’s and a SOM that includes an ADI transceiver.

Comparison of Radar and Lidar Sensors for Autonomous Vehicles – Performance and Market Trends

Radar and LiDAR sensors are the key sensors for the future autonomous vehicles enabling the detection of vehicles, people and other moving or fixed objects around the vehicle. Recent advances in these fields have significantly improved their performance and features. This talk will discuss the technologies used and applications of these sensors for self-driving-vehicles (SDV). […]

Bigger Than You Are: The Emerging Role of Fractal Superscatterers

Metamaterials present emerging roles in contemporary RF applications. This talk describes one important application, specifically fractal metamaterials, as enhanced reflectors. Gain enhancement at selected and controllable frequencies can be substantial, meriting the moniker ‘superscatterers’.  Looked at as radar targets, superscatterers can present a radar cross section(RCS) far greater than that expected from the surface geometry […]

ADAS Sensor Design & Placement

Modern vehicles contain countless antennas and sensors which are crucial to the overall performance and safety of autonomous and assisted driving systems. All these components need not only function correctly in isolation, but also in close proximity to one another. System integrators cannot rely on combining all these systems in the prototype phase as late […]

Today’s Satellite Broadband Landscape: LEOs, MEOs, GEOs and Megaconstellations

In a connected society, it is challenging to fathom that the year 2019 marked the first year in which more than half the world had access to the Internet. For decades, but in particular the past ten years, tremendous efforts from governments and the private sector have been made to bring more individuals online, and […]

Scanning Radar Horizons: Near & Far

Once a relatively staid technology discipline where innovation timelines were measured in years, radar has seen an unprecedented rate of growth and proliferation fueled by many disparate markets including the military/civil, UAVs, automotive, autonomous vehicles both ground-based and airborne, commercial products and medical—to name a few. Military radars are continuing to evolve ever more sophisticated […]

A New Approach to Radar Signal Analysis

Secondary surveillance radar (SSR) and Identification Friend or Foe (IFF) radar are essential tools for safe and secure aviation. While the radar systems have evolved, many of the test challenges have remained constant. Depending upon whether one is designing, characterizing, installing, maintaining, or troubleshooting an SSR system, one may have different requirements for testing the […]

Residual Phase Noise Measurement of Components for Advanced Radar Systems

Phase noise becomes an increasingly important system-level specification for electronic test equipment, communications systems, and radar systems. Modern radar systems are trying to extract more information about the targets they track and provide the ability to track even slow moving targets in the presence of clutter. The lower the phase noise, the better this will […]

Drone Based Mobile Quantum Links

Quantum links have been demonstrated using satellite and fiber. Here, we propose a new type of quantum link using drones, for mobile connections with high flexibility. We demonstrate the first drone-based entanglement distribution, to work in multi-weather conditions including daytime and rainy nights. Moreover, we show that the drones node can be interconnected in air, […]

Advanced Simulation Tools for Automotive Radar Integration and Virtual Drive Tests

Automotive OEMs are moving towards the inclusion of several safety systems, which are covered by several sensors. Many new functions are being added to assist the driver to avoid accidents that might be caused by different road scenarios. The new ADAS (Advanced Driver Assistance Systems) systems are mainly: lane change assistants (LCA), blind spot detection […]
