Over the past 15 years, correlation radiometry techniques have been developed to detect the small-amplitude, high-frequency electron temperature fluctuations to which standard electron cyclotron emission measurements are insensitive. In this paper we review the principles of these techniques and summarize recent core electron temperature fluctuation measurements and their impact on understanding turbulent transport.
