ResumoFrom the formula for the generalized response of a correlation interferometer to an incident partially polarized radio wave, the forms for the four output channels from each interferometer in the Westerbork telescope are developed. Then, the means of instrument gain, phase, and polarization calibration are detailed and the solutions for the four Stokes parameters obtained. The advantages and disadvantages of the technique are briefly discussed. The Appendix contains a derivation of the basic initial formula. (auth)
