Ka-band Doppler Polarimetric Scanning Radar (MRIAN-Ka-C-S-0.5)
The MRIAN-Ka-C-S-0.5 is a multipurpose system that can be used as meteorological radar, or as air, surface, and maritime surveillance radar. It is designed for long life time, unattended operation at unmanned sites. The radar enables for real-time remote control, monitoring, diagnostics, and access to measured data. Continuous automatic calibration of the radar sensitivity is introduced.
The MRIAN-Ka-C-S-0.5 is intended for volumetric or surface observations, real-time measurements, imaging, and storing of
- Radar reflectivity profiles at co- and cross-polarizations,
- Radial mean velocity profiles at co- and cross-polarizations,
- Velocity variance at co- and cross-polarizations,
- Doppler spectrum at co- and cross-polarizations,
- Linear depolarization ratio (LDR),
- Detection of targets and measurement of their characteristics (RCS, coordinates, velocity)
