Context: The Union Ministry of Earth Sciences approved the installation of an X-band radar in Wayanad to improve monitoring and prediction of weather conditions, specifically for early warnings related to landslides and floods.
About X-band Radar:
| Feature | Details |
| Purpose | Monitors smaller particles like rain droplets or soil movements. |
| Frequency Range | 8-12 GHz (corresponds to wavelengths of 2-4 cm). |
| Technology | Uses Doppler radar and Rayleigh scattering to detect object movement. |
| Resolution | Produces higher resolution images due to shorter wavelength. |
| Range | Shorter range compared to lower frequency bands, ideal for localized studies. |
| Application in Wayanad | Will monitor soil movement for landslide warnings and high temporal sampling. |
| Meteorological Use | Tracks clouds, rain patterns, and storm formation in real time. |
| Limitations | Shorter range due to higher attenuation of the signal. |
| Previous Installation in India | First X-band radar installed in New Delhi in 1970. |
