India’s first Avalanche Monitoring Radar

• 30 Sep 2022

The Indian Army and the Defence Geoinformatics and Research Establishment (DGRE) have jointly installed the Avalanche Monitoring Radar, first of its kind in India, at an altitude of 15,000 feet in north Sikkim.

• Besides being used for detection of avalanches, this radar can also be employed to detect landslides.
• This radar has the capability to detect avalanches within three seconds of their triggering and will assist in saving valuable life of troops and civilians as also vehicles in super high altitude areas.
• The avalanche radar was made operational by Defence Research and Development Organisation’s wing DGRE, which is involved in forecasting and mitigation of avalanche hazards faced by Indian Army in the Himalayan region.

Working Principle/Features

• The radar uses a series of short micro wave pulses which are scattered at the target and can detect an avalanche in less than three seconds.
• The radar, which can permanently scan the targeted slope for avalanche release and track its path and its size in case it is triggered, can “see” through snow, fog as well as in the night, making it an all-weather solution and covers an area of two sq/km obviating the requirement to place additional instruments in dangerous avalanche prone areas.
• The radar is also linked to an alarm system enabling automatic control and warning measures in case an avalanche is triggered. Images and videos of the event are automatically recorded for future analysis by the experts.
