Rethinking RF: How Time-Domain Methods Are Reclaiming Ground in 5G and Radar Engineering
As 5G New Radio deployments grow denser and wideband radar systems push the limits of spectral complexity, frequency-domain analysis is proving insufficient on its own. Engineers at defense and telecom research facilities across the United States are rediscovering the diagnostic power of time-domain techniques—from transient interference hunting to precision pulse characterization. This article examines why the pendulum is swinging back, and what tools are making that transition practical.
