LWIR THERMAL PHYSICS IN DISASTER SAR

Long-Wave Infrared (8–14 μm) microbolometers measure emitted surface blackbody radiation. They do NOT see through solid opaque concrete or deep soil. Rather, thermal sensors isolate the living 37.0°C body heat radiated through void openings, fissures, or shallow mud cover where optical cameras suffer total contrast failure.

KEY DRONE SUBSYSTEMS (BOM OVERVIEW)

1. COMPUTE:

Arduino UNO Q (Qualcomm QRB2210 + STM32U585) in 40g module.

2. PERCEPTION:

Dual-gimbal 1080p visible EO + Radiometric LWIR (8–14μm) thermal sensor.

3. AVIONICS:

MPU6050 IMU, MS5611 Baro, Downward ToF LiDAR for ground altitude.

4. DATALINK:

Semtech SX1262 LoRa 868MHz transceiver for 3–5 km P2P mesh.

ENGINEERING LIMITATIONS & FIELD CONSTRAINTS:

• Thermal detection performance degrades if ambient temperature approaches human core temperature (thermal inversion at >36°C).
• The Tait-Bryan ray-casting calculation assumes locally flat ground elevation; severe irregular vertical cliff terrain requires DEM terrain fusion.
• LoRa P2P range is subject to Fresnel zone clearance and dense concrete obstruction attenuation in deep urban gorges.

Stakeholder Impact & Operational Value

TRAPPED VICTIMS

Rapid discovery within Golden 72 Hours; location transmitted to first responders before manual scouts arrive.

NDRF / SDRF TEAMS

Advance hazard mapping prevents secondary entrapment from live cables, gas leaks, and unstable voids.

DISASTER AUTHORITIES

Offline unified GIS tactical map delivers real-time survivor count and coordinates with zero cellular infrastructure.

DISTRICT GOVERNANCE

Cost-effective local deployment at ~₹1.2–1.4L BOM compared to ₹12–14L imported enterprise platforms.
