Panaji: In addition to military and reconnaissance satellites that capture high-resolution images, track radar signals and provide GPS services, unmanned aerial vehicles (UAVs) are increasingly being deployed for continuous, real-time surveillance over specific conflict zones and along borders.Elaborating on these developments, D Seshagiri, director of the Naval Physical and Oceanographic Laboratory, Defence Research and Development Organisation (DRDO), ministry of defence, Kochi, will deliver a lecture titled “Eyes in the Sky, Ears in the Waters” at the National Institute of Oceanography (NIO), Goa, on Monday as part of the institute’s Open Day celebrations. The lecture will focus on technologies that help detect, track and identify underwater vessels, particularly submarines, and have the potential to expand surveillance coverage across India’s maritime zones, including its Exclusive Economic Zone (EEZ).The lecture is also expected to highlight the growing role of integrated aerial and underwater sensing technologies in strengthening India’s surveillance capabilities by combining information gathered from different platforms to monitor activity across the country’s maritime and territorial boundaries.“The talk focuses on the core technologies used for surveillance of our sovereign territories. The eyes in the sky refers to the aerial and space-based surveillance technologies that provide a high-altitude or orbital view of the Earth to monitor movements, gather intelligence, and track weather,” the NIO stated.The ears in the waters refers to maritime surveillance technologies, including those used in anti-submarine warfare, which play a crucial role in monitoring underwater activity and detecting potential threats in the maritime domain.“This primarily employs underwater acoustic technologies used to detect, track, and identify vessels, especially silent submarines or UIVs, and map the ocean floor,” the NIO stated.The public lecture will begin at 4pm at the NIO Goa auditorium in Dona Paula. The event will provide an opportunity for members of the public to learn about the technologies used in aerial and underwater surveillance and their importance in monitoring India’s maritime areas.
