Abstract: BaR-SPOrt is a project to measure the linearly polarized emission of 20°×20° sky patches from a stratospheric balloon, at 32 GHz and 90 GHz. It consists of correlation polarimeters for direct measurements of the Q and U Stokes parameters, coupled to an optics providing a beam of 0°.5 (32 GHz) and 0°.2 (90 GHz). The instrument design is described. Particular emphasis is put on the hardware solutions adopted to reduce the systematic effects in high sensitivity polarization measurements. © 2002 American Institute of Physics.
