Paper Abstract

Coherent radiometers have been used for decades in the detection of polarization of astronomical signals. Recent success in detection of intensity fluctuations of the Cosmic Microwave Background (CMB) has created great interest in the potential measurement of CMB polarization. Detection of polarization at predicted levels may stretch the sensitivity of today's radiometers. I will review the state-of-the-art of receiver front-ends, discuss their application to polarimeter design in experiments, both existing and under development and finally describe the prospects for massive arrays for the detection of CMB polarization.
