- The Union Ministry of Earth Sciences approved an X-band radar to be installed in Kerala’s Wayanad district.
- The device uses radio waves to determine the distance, velocity, and physical characteristics of objects around the device.
- The Doppler radar relies on Rayleigh scattering, when the scatterer is much smaller than the wavelength of the radiation.
- An X-band radar is radar that emits radiation in the X-band of the electromagnetic spectrum: 8-12 GHz, corresponding to wavelengths of around 2-4 cm.
- The smaller wavelengths allow the radar to produce images of higher resolution.
- X-band radars have a relatively shorter range.
- The new radar is expected to be able to monitor the movements of particles, such as soil, to inform landslide warnings.
- The first indigenously designed and manufactured X-band storm detection radar was installed in 1970 in New Delhi.
