Maritime radar operates in one of the harshest signal environments known to defence engineers. Sea clutter — the unwanted echoes reflected from ocean waves, spray and surface turbulence — masks genuine targets and overwhelms operators with false returns. As threats grow smaller and faster, the ability to separate signal from noise in real time has become a national security priority. This is precisely why AI-Based Clutter Rejection sits at the top of the twelve core problem statements at the BDTS Hyderabad Strategic Colloquium 2026.
Why Sea Clutter Is So Difficult to Suppress
Traditional radar systems rely on fixed thresholds and constant false-alarm-rate processing. These techniques struggle when sea states shift rapidly or when low-observable vessels hug the surface. The clutter statistics change minute to minute, and rigid filters either blind the radar to real contacts or flood the screen with ghosts. Indian coastal surveillance, spanning more than 7,500 kilometres of coastline, demands adaptive intelligence rather than static rules.
How Artificial Intelligence Changes the Game
Machine learning models trained on vast libraries of clutter signatures can learn to distinguish the chaotic texture of waves from the coherent motion of a boat, submarine periscope or sea-skimming missile. Neural networks perform real-time suppression, continuously re-tuning themselves to the current sea state. The result is cleaner detection, fewer false alarms and faster operator decisions — exactly the ready-to-integrate capability that Lead System Integrators such as BEL and BDL seek.
The BDTS Opportunity for Startups
The Hyderabad colloquium is a curation and selection platform, not a conventional exhibition. Deep-tech startups solving this challenge move directly from lab to market, earning technical feedback and a route into the national defence supply chain. Shortlisted innovators progress toward the BDTS 2027 Grand Finale in New Delhi, gaining exposure to the Ministry of Defence and DRDO procurement pathways. For anyone building indigenous radar intelligence, this is the platform to be seen.
