Eldes - Model WR-10X - Metrological Radar System
From Radar Meteorology
The WR-10X is a valuable tool for real-time monitoring of weather phenomena in areas with complex topography. It can be used advantageously at both urban and regional scales, or as a gap filler in an existing network. A mobile version can be deployed quickly in cases where meteorological alerts occur in areas with significant hydrological risks, as an important tool for civil protection emergencies. A real portable weather radar. The radar can be installed alone or in a cluster, in both fixed and mobile configurations. Cluster networking allows the system coverage to be extended practically without limit. The resulting image products are mosaics integrating the data collected by all the sensors composing the network.
- The WR-10X is an innovative radar system designed for realtime monitoring of weather phenomena.
- Thanks to its small size and weight, the WR-10X can be easily installed in a fixed or mobile platform.
- Its low purchase and operating costs allow this new monitoring instrument to be used in a wide variety of applications.
Thanks to the use of the latest technology, the capital, installation, and operating costs of WR-10X radars networks are very attractive alternatives to the traditional high-power big-size weather radar approach.
The control and display software has a very intuitive graphic user interface, which allows good skills in radar operation and data interpretation to be achieved after only a short training period, even for a user without specific knowledge in radar meteorology.
Once a scanning schedule has been programmed, the system will begin acquiring data and generating 'products', which are images of the weather events detected, with color levels proportional to weather intensity, superimposed on a local map, with adjustable distance and time scales.
A comprehensive set of the most common weather products is provided with the system, and thanks to the open software
architecture, additional or customized products can be easily added later.
Reliability, maintainability, and ease of installation were fundamental design objectives for the WR-10X. The system can be remotely controlled, operated, and tested, so there is no need for easy access to the radar site.
The WR-10X operates in X band (9400-9500MHz), allowing the use of a very compact antenna while still preserving good angular resolution. The radar electronics are integrated into the antenna pedestal and everything, with the exception of the server PC, is contained inside a small radome. This integrated configuration allows the installation time and the cost of the infrastructure to be drastically reduced. The power consumption of the WR-10X (ca. 200W) is tiny compared to traditional high power weather radars, easing installation in remote sites. The WR-10X has a coverage range of 108 km for medium to strong precipitation, and about 35 km for medium to light precipitation.
Any communication channel supporting the TCP/IP protocol can be used for the WR-10X networked radar sites and control centre, including standard wireless or switched telephone networks.
Despite its low cost, the WR-10X provides all the features necessary for accurate and complete radar observations and the assessment of weather phenomena.
A 'pencil-beam' antenna with equal beam widths in both elevation and azimuth and fully automated elevation control, allow acquisition of three-dimensional sets (volumes) of polar data for generating meteorological products and RHI scans.
The cost-effective WR-10X-CE version features single elevation azimuthal scans hence generating only the simplest 'weather products', still allowing very accurate and sensible storms detection and monitoring. The WR-10X-CE version can be later upgraded to the full fledged one with simple operations.
The radar products listed below consist of maps representing various weather parameters such as reflectivity, instantaneous and accumulated surface rainfall, from a single radar or from a combination of networked sensors (mosaic).
The radar software can be used to display both real-time and archived products with 'movie-loop' functionality and other display tools.
Each radar can be individually programmed with a particular scanning schedule to acquire and record data in a synchronous way. The software allows integration of the radar data with other sensor information, such as rain gauge data, satellite images, etc., to create customizable multi-sensor views.
