October 24 , 2024 7 days 118 0
  • 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.
