|| Vertically pointing Cloud Radar MIRA-10 ( X-band Vertical Cloud Radar )
|| Cloud Radar MIRA-35C ( Compact Vertical Pointing Cloud Radar )
MIRA-35C is a compact and very price competitive alternative to Metek’s classical MIRA-35 as a limited reduction of sensitivity with respect to MIRA-35 is acceptable for most investigations of cloud structures, for example for cloud seeding and climatological studies.
The radar electronic is accommodated in a hermetically sealed box, making handling, installation and operation as convenient as possible The size of the complete radar is mostly dominated by the selected sizes of the Cassegrain antenna which are offered as 50 cm and 100 cm parabolic versions.
Due to the adapted transmit power, the MIRA 35-C does not require air conditioning and waveguide pressurization, reducing efforts for installation, operation and maintenance.
