ABSTRACT: New technologies developed for modern applications continually advance the design and performance standards of civilian and military radar systems. Excluding the impact of COVID-19 in 2020, passenger air travel has increased between 4% and 8% every year for the last 10 years, while military radar systems are under constant pressure to counter increasingly sophisticated threats. As radar systems continue to evolve, the demands on instrumentation used to test these advanced radar technologies have never been greater. While the test requirements vary depending on the type of radar system, RF power measurements remain a constant, indispensable element to verify radar performance. This article provides an overview of RF power measurements critical to the proper operation of today’s radar systems, as well as the state-of-the-art in related test equipment.
