Automotive Grade Radar. Indian Intelligence.
DRWIG — Automotive-grade Radar With Indigenous Genius — is a complete hardware-software radar stack developed in India. Calibrated for Indian roads, weather, and traffic. No imports required.
DRWIG in Action
Real-world radar perception — point cloud fusion, object detection, and tracking on Indian roads.
Ownership Architecture: Who Builds What
A clear division of responsibilities between OEM / System Integrators and the Gahan AI sensor platform — enabling plug-and-play ADAS integration compliant with Indian standards.

Three Verticals. One Platform.
DRWIG's modular architecture serves distinct markets with the same core technology advantage — indigenous, calibrated, and production-ready.
Automotive ADAS
Level 2+ to Level 4 autonomy enabling features for passenger cars, commercial vehicles, and two-wheelers operating on Indian roads.
- Adaptive Cruise Control (ACC)
- Automatic Emergency Braking (AEB)
- Blind Spot Detection
- Lane Change Assistance
- Pedestrian & Two-Wheeler Detection
- Bharat NCAP compliance
Smart Infrastructure
Traffic management, pedestrian flow analysis, and smart city sensing — deployed at intersections, highways, and transit hubs across India.
- Vehicle speed and classification
- Pedestrian counting and flow
- Queue length estimation
- Wrong-way driver detection
- All-weather operation (rain, fog, dust)
- SCADA / V2X integration
Defence & Security
Perimeter intrusion detection, drone detection, and force protection for defence establishments and critical national infrastructure.
- Ground surveillance radar
- Perimeter intrusion detection
- Micro-UAV / drone detection
- Vehicle classification at range
- Integration with C2 systems
- MIL-STD environmental ratings
Imported Radars Were Not Built for Bharat
Every imported radar sensor on the market today was designed and calibrated for Western driving conditions. German autobahns. American interstates. These models have never seen the organised chaos of a Mumbai flyover during rush hour, or the cattle that appear on NH-44 after dark.
The result: imported ADAS systems in India suffer from far higher false-positive rates, degraded performance in monsoon conditions, and fundamental blind spots around two-wheelers — which account for 70% of Indian vehicle population.
DRWIG is trained and calibrated from the ground up on 10 TB of radar data collected across Indian roads, seasons, and traffic conditions. It understands Indian driving.
Two-Wheeler Optimised Detection
Specialised ML models trained to reliably detect motorcycles and scooters — the majority of Indian road users — at close range and in dense traffic.
Monsoon & Dust Calibrated
Trained on radar clutter data from Indian monsoon rain, fog, and dust storms. False-positive rate 40% lower than unadapted imported solutions.
Dense Traffic Scene Understanding
Optimised for Indian urban traffic densities — 5–10x higher vehicle density than European scenarios for which most imported radars are calibrated.
Sovereign Supply Chain
Zero dependence on foreign sensor supply chains. Designed in India, manufactured in India. Critical for defence and strategic applications.
India's 2027 ADAS Mandate
The Bharat NCAP programme mandates ADAS safety features in all new passenger vehicles by 2027. Radar is the only sensor that can reliably deliver these features in Indian conditions — and the demand will be enormous.
