The Wind Profiler Radar Data Processing System

Wind profiling radar is a radar echo Doppler frequency shift measure high-altitude wind direction, wind speed distribution equipment. The principle is that when a bunch of radio wave emission to the atmosphere, due to scattering of air masses with the wind drift, causing a certain amount of echo signals generated Doppler frequency shift, by measuring the frequency shift of echo signals to calculate the value of the radar beam along the radial the wind speed sub-value. Wind profiling radar is a high degree of automation of meteorological equipment, controlled by computer, auto-switching beam point detection, automatic data collection, automatic processing to form products, automatic transmission, with high reliability, stability, can be all-weather long-term continuous run. Wind profiling radar is used to compensate for conventional high-altitude wind is not enough to detect the density of space-time, but also as a meso-scale severe weather monitoring system as part of stroke profiles of atmospheric observations with high time resolution.Wind Profiler Radar Data Processing system is through the establishment of a series of hardware, software and network environment, to develop and install in all aspects of running the appropriate software applications, using a unified data structure, a unified data format, the completion of data processing, meteorological products display, to detect data quality assessment, monitoring operation of wind profiler radar, and radar wind profiler routine maintenance management, file backup, data backup functions.In this paper, the system used in the process of developing the technology introduced and discussed in the introduction of the system development of J2EE-based B / S model, introduced J2EE, Portal, XML, Microsoft SQLServer and other technologies; On this basis, compliance with software engineering principles and methods of systems analysis, the use of UML for system modeling of the function, the end of each functional module of the Design and Implementation.The data processing system is composed of four operational layers: basic security layer, data management, business process layer, the application presentation layer. This paper discusses the application of its business processing layer and presentation layer. The two main functions of the business layer: wind profiler radar network to monitor the operational status of equipment; remote equipment failure alarm; wind profiler radar data quality analysis and evaluation; wind profiler radar raw data processing; wind profiler radar probe data quality control; wind profiler radar, secondary products generated; wind profiler radar data on the historical status of the statistical analysis; wind profiler radar network operational status and fault diagnostic data archiving backup; wind profiler radar network data products and secondary products archive backup; wind profiler radar network data products and secondary products display, as well as Web release.Data processing systems have the following capabilities: use of a unified data structure, data format, the completion of data processing, the product appeared on the day-to-day maintenance of data management, with file backup, data backup functions.
