We highlight some of the strengths\, address some of the limitati ons and present ways in which these may be effectively overcome.\n\nDuring recent years\, compressive sensing (CS) and sparse sampling based techniq ues have been successfully deployed to tackle a wide variety of free-field measurement applications including radar imaging\, cylindrical and spheri cal near-field measurements\, far-field reflction suppression\, and for ar ray antenna measurement and diagnostics. For the case of measuring massive MIMO arrays\, CS has been successfully used to dramaticaly reduce the num ber of measurements required to verify the antenna array's excitation in a production test environment using either spherical or planar acquisition geometries. These have largely followed the same general approach of creat ing the sparsity required by CS by using the total variation method which involves subtracting the measured far-field or near-field of the assumed d efective test array antenna from that of a known reference "gold standard" array measured under identical conditions.\n\nProfessor Stuart Gregson ha s been working in the space\, aerospace\, and communications sectors for n early thirty years\, and as of 2019 is Director of Operations & Research a t Next Phase Measurements. In 2017 he was promoted to honorary visiting pr ofessor in the School of Electronic Engineering and Computer Science at Qu een Mary University of London. He received his BSc degree in Physics in 19 94 and his MSc degree in Microwave Solid State Physics in 1995 both from t he University of Portsmouth. He received his PhD degree in 2003 from Queen Mary University of London with near-field antenna measurements and statis tical pattern recognition as his main subject areas. From his time with: A irbus\, Leonardo\, NSI-MI\, NPL and Next Phase Measurements\; Prof. Gregso n has developed special experience with near-field antenna measurements\, finite array mutual coupling\, computational electromagnetics\, installed antenna and radome performance prediction\, compact antenna test range des ign & simulation\, electromagnetic scattering\, 5G OTA measurements and ha s published more than a hundred peer-reviewed research papers on these top ics regularly contributing to and organizing industrial courses in these s ubject areas. At the end of 2007 he was the lead author of the research te xt\, Principles of Planar Near-Field Antenna Measurements\, and in 2014 he co-authored a second text\, Theory and Practice of Modern Antenna Range M easurements\, both of which are now in their second editions and are publi shed by the IET in their Electromagnetic Waves Series. In 2008 and 2023 he received the AMTA Best Technical Paper Award\, and in 2015 he presented t he AMTA Sunday Short Course on Near-Field Measurement Error Analysis & Com putational Electromagnetic Modeling\, and currently organizes and presents the IET's annual short course on Modern Antenna Range Measurements. He is a Fellow of the Antenna Measurement Techniques Association\, a Fellow of the Institution of Engineering and Technology\, a Fellow of the Institute of Physics and is a chartered Engineer and Physicist. In 2018\, Prof. Greg son was elected to the AMTA Board of Directors where he served first as Tr easurer\, then as Vice President and now as Chair of the AMTA Growth Commi ttee.
