Abstract：Polarimetric microwave radiometer is a new passive microwave remote sensor used to measure ocean surface wind field.Digital correlator is the core component of polarimetric radiometer.Compared to analog correlator,the digital correlator radiometer has the configurable,highly integrated and easy-to-control features/At the same time,digital technology will bring radiometer quantization error and phase jitter.Detailed error analysis is the way to verify the feasibility of digital technology in fully polarimetric microwave radiometer.The quantitative error is analyzed.According to practical application,the error caused by multi-bit digital technology can be ignored in the overall system.
