X-band radar

Current Context : The Union Ministry of Earth Sciences has approved the installation of an X-band radar in Wayanad, Kerala, following severe floods and landslides.

ABOUT X-BAND RADAR:

• Frequency Range: Operates in the 8-12 GHz range, allowing for high-resolution imaging.
• Applications: Monitors particle movements, such as soil, aiding in landslide warnings.
• Real-Time Monitoring: Capable of rapid sampling to detect changes in particle movement.
• Weather Observation: Useful for studying cloud development and light precipitation due to its ability to detect small water particles​

WHAT IS RADAR?

• Radar (Radio Detection and Ranging) uses radio waves to determine the distance, speed, and characteristics of objects.
• Functionality: Emits a signal that reflects off objects, with the return signal analyzed for information.
• Common Use: Weather radar is a significant application, helping to track weather patterns and precipitation​
• Weather radar, also known as a Doppler radar, is a common application of this device. The Doppler effect is the change in frequency of sound waves as their source moves towards and away from a listener.
