Space Domain Awareness and Associated High-Power Radar Transmitter Technologies

Currently a large amount of debris, potentially lethal to resident space assets, is orbiting Earth. While a handful of countries keep track of it, a significant gap is emerging between the debris density, its growth, and the ability to track it and monitor it on a continuous basis. This article takes a close look at the key high-power radars that are entrusted with this difficult task and examines and assesses the high-power transmitter technology and its advancement over the past four decades.
