Measurements of Phased Array Beamforming Dynamics and Transients at mm-Wave Frequencies
The required steering and settling speeds for many phased array systems are increasingly demanding to support overall data throughput, scanning requirements, and for other reasons. As a result, studies of the beam dynamics become more important at both design and characterization levels. The measurements to perform those studies may need to have acquisition speeds on the ns scale, low-latency-triggering requirements, fast receiver scanning in space and/or frequency and other features. This talk will explore some possible measurement structures at mm-wave frequencies, execution and uncertainty challenges, and a sampling of interesting beam behaviors that can be revealed with enough time and receiver resolution.
