Abstract
Microwave united measuring and control system (MUMCS) is one of the most
popular measuring and control equipments and plays an important role in the
measuring and control equipment of aircraft in China. As the main data source of
MUMCS, remote measuring data (RMD) is the primary basis of aircraft orbit
measuring and control. Moreover, It is very important to improve the processing
precision and capacity to singular data of MUMCS remote measuring data.
Treated as a crucial part of aircraft measuring and control, the processing of
RMD is also the primary basis of evaluating condition of measuring and control
equipments (MCE) and aircraft spacing pose. Data processing has developed from the
simply afterwards processing to the sub real-time, real-time and intelligent process.
After the explanation of basic theory of work (NN) and thorough
consideration in character of real-time data processing and intelligent processing,
depending on the many years working experience in afterwards processing of outside
measuring data, the author applied wavelet multi-resolution analysis and NN to the
data processing, mainly aiming at the existent questions in the data processing and
developmental orientation of outside measuring data processing.
