Based on previous developments (X-band GB-SAR), the Rain Radar is a new approach in meteorological radar technique to get complete Doppler spectra of hydrometeors in a height between 100 and 8000 meters. It is highly reconfigurable for different cell resolution (1.5m, 15m 50m & 100m). It will be able to extract appart from rain rates, the raindrop velocity. This Rain Radar operates in FM-CW mode at X-band (9.65GHz), the antennas are TV-SAT offset parabolic reflectors. We are working in its hardware configuration and calibration (reflectivity and Doppler detection).
The last inprovement has been the substitution of the feeders of the parabolic reflectors. Taking advantage of additive manufacturing, we have built a pair of corrugated circular horn antennas with PLA, that have been metalized by means of copper electroplating.
Both antennas, the corrugated horn antenna and the parabolic reflector have been measured (thanks, Sebastián Blanch) in our Anechoic Chamber in order to check their performance.
Last winter we had some snow days in Barcelona, we could check the system under these conditions.
Take a look at this video, it shows the march, 20th 2018 SnowStorm evolution in Barcelona.
During last months we are working hard in a FULL-POL version of the RADAR. Please, stay tuned.
