Network Architecture for Small X-band Weather Radars – Test Bed for Automatic Inter-calibration and Nowcasting
In recent years the use of small inexpensive Xband radars for meteorological and hydrological purposes has increased significantly. Compared to the traditional C-band and S-band radars the X-band weather radar has the advantage of high temporal and spatial resolution and low financial cost; however, the trade off is attenuation due to X-band technology and short range due to the higher spatial ...
متن کاملOptimal placement of weather radar network in complex terrain using swarm intelligence
This work proposes an accelerated particle swarm optimization (APSO) approach for the optimal placement problem of small low cost x-band mountain weather radars. Given a finite set of weather radars, a network is produced such that the geographical coverage area is maximised. By taking in consideration terrain blockage and low level radar beam elevation restrictions, the proposed method is capa...
متن کاملLow-cost Vector Network Analyzer for Biomedical Applications
A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...
متن کاملInteractive comment on “Precipitation and Microphysical Processes Observed by Three Polarimetric X-Band Radars during HOPE” by X. Xie et al
This paper presents some data from an two months experiment. The examined dataset included three polarimetric X-band weather radars supplemented by MRRs, disdrometers and rain-gauges. The focus of the paper is on the radar observations. The recorded rain events were of low intensity and this didn’t permit a more advanced evaluation of radars performance. Thus, instead of just showing some daily...
متن کاملRainfall retrieval from polarimetric X-band radar measurements
Dual polarization radars have shown considerable improvement of quantitative estimation of rainfall rate and raindrop size distribution (DSD) parameters. Most studies have been done with S and C-band radars and only a few studies with higher X-band weather radars. X-band radars have the advantages of lower cost and higher differential phase shift but with higher attenuation too. Furthermore, th...
