Study of Meterological Phenomena as Related to the Errors in Radio Interferometer Tracking Systems

摘要

Meteorological parameters are responsible for certain errors in radio interferometer type tracking systems. This report considers these tracking errors as being a combination of 'bias' and 'noise' errors. Bias errors are defined as having periods greater than several minutes, while noise errors are defined as having periods ranging from about a second to several minutes. Ground-based and airborne meteorological instrumentation for the measurement of the appropriate meteorological parameters is described. Data acquisition, reduction, and analysis procedures for the determination of both bias and noise errors are described. (Author)
