High Resolution Weather Radar through Pulse Compression
In order to evaluate pulse compression for use in phased array weather radar systems, modifications to the Time-Series Weather Radar Simulator have been made which incorporate phase-coding into its functionality. This allows for evaluating the performance of various pulse compression schemes under controlled conditions. Barker-coded pulses with matched and mismatched filters were examined in re...
متن کاملEfficient Storage of Weather Radar Data
Weather radars produce large amounts of data and this has important implications for the archiving and analysis of data. The need for methods to deal with weather radar data sets will only increase as the United States National Weather Service (NWS) continues deployment of its 137 WSR-88D radars as part of the NEXRAD program. In this article we describe a compression and archiving strategy for ...
متن کاملOverview of Radar Data Compression
Radar data is routinely transmitted in real-time from the coterminous United States (CONUS) radar sites and placed on the Internet for incorporation into nowcasting, hydrology and modeling applications in near-realtime. Radar data are also archived for on-demand retrieval by the National Climate Data Center (NCDC). Data compression is used operationally to reduce bandwidth and storage requireme...

متن کاملImproving Weather Radar Data Quality for Aviation Weather Needs*
A fundamental function of any aviation weather system is to provide accurate and timely weather information tailored to the specific air traffic situations for which a system is designed. Weather location and intensity are of prime importance to such systems. Knowledge of the weather provides “nowcasting” functionality in the terminal and en route air spaces. It also is used as input into aviat...
