Abstract全极化微波辐射计是一种用于海洋表面风场测量的新型被动微波遥感器.数字相关器是全极化辐射计的核心部件.数字相关器的应用相对于模拟相关辐射计具有可配置、集成度高和易于控制的特点.同时,数字化技术会给辐射计带来量化误差和相位抖动误差.具体的误差分析验证了全极化微波辐射计中数字化的可行性.文中详细分析了定量误差,并根据实际工程应用说明了多比特数字化带来的误差可以在系统整体误差中忽略.
Other AbstractPolarimetric 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.
