Abstract

The polarimeter has three receiving antennae (1-3) which have been calibrated for polarisation at the frequency and direction under consideration. Each receiving antenna is associated with a receiver path (4-6), pre-calibrated at a constant phase. The antennae outputs are coupled to processors (7,8) which determine the phase difference (epsilon 1,epsilon 2) between two coupled antennae. The polarisation (9) of the incident EM field is also determined from the calibration and measured data.
