The squat cylinder is the primary calibration device used in most indoor RCS measurement chambers. DSC offers a full line of precision squat cylinders, including those defined by AFRL/NIST as 375, 450, 750, 900, 1500, 1800, 2800, and 3360. DSC offers closed volume designs to rest on foam columns or open volume models to fit your top-hat style AZ/EL positioners. Full-wave and physical optics RCS data are available based on electrical size.
