02 August, 2024 – As rescuers navigate harsh conditions to locate survivors trapped in collapsed buildings after a devastating landslide in Kerala’s mountainous Wayanad district, time is critical. The disaster has claimed over 300 lives, with hundreds still missing.
Rescue operations, now in their fourth day as of Friday, have expanded to include drone-based radar technology to locate survivors.
Advancements In Drone Technology
Modern drone technology allows for low-altitude flights, particularly at 120 meters above the ground. This enables precise and flexible flight paths with minimal preparation, surveying areas up to 40 hectares per flight. The coverage area is limited by the drone’s endurance, which has been improving steadily over the years.
Phased-Array Radar
Phased-array radars offer significant advantages over traditional mechanical systems by using electronically steered antennas that rapidly switch beams across various directions without physical movement. This results in faster scanning times and better tracking accuracy. Reconfigurable phased-array radars provide adaptability in target detection as well as tracking by dynamically modifying beam shapes as well as frequencies.
Applications In Surveillance And Monitoring
Mounting these advanced radar systems on drones allows authorities to deploy powerful surveillance platforms at critical locations or specific areas. These drones provide continuous aerial monitoring and transmit real-time radar data to command centers. This capability is invaluable for border surveillance, tracking enemy activities, and supporting tactical operations in complex environments.
