New active electronically-scanned arrays (AESAs) are being used for radar systems in satellites and unmanned aerial vehicles. As these systems are deployed in new and novel ways, size and performance requirements are becoming critical and are being addressed through innovative architectures and system capabilities. This white paper examines these technology trends and presents several examples where advances in NI AWR Design Environment are supporting next-generation AESA and phased-array radar development.
Cable assemblies are critical to obtaining correct test results and signal integrity. Proper care and handling of cable assemblies and connector interfaces is critical to insuring accurate operation. When connectors are not properly mated or cared for, there is a risk of damaging test ports and mating devices.
To address our rapidly approaching, hyper-connected future and the unprecedented demand on current 4G wireless networks, researchers at the University of Bristol and Lund University set out to test the feasibility of massive MIMO as a viable technology for 5G networks. Using the NI MIMO Prototyping System, the team was able to rapidly test new ideas on their way to implementing the world’s first live demonstration of a 128-antenna, real-time massive MIMO testbed and set two consecutive world records in spectral efficiency.
This paper presents a new predictive capability for simulating massive MIMO antennas and beamforming in dense urban propagation environments. Wireless InSite's MIMO capability is used to show predictions for SINR at specific device locations and the actual physical beams, including unintentional distortions caused by pilot contamination.
