A detailed description of the design and calibration of a multimixer far-infrared scattering system for the study of collective plasma density fluctuations is presented. The apparatus permits either the determination of single-shot wave dispersion data or angularly resolved scattering data at multispatial locations during a single plasma discharge. Typical scattering data from spontaneously occurring low-frequency microturbulence as well as from kinetic Alfven waves (generated during ICRF heating) in the UCLA Microtor tokamak are presented.
