Sahara

Autonomous UAV-borne SAR payload delivering on-demand, all-weather situational awareness.

Product descripton: Sahara by Harmattan AI

SAHARA is an autonomous UAV-borne synthetic aperture radar (SAR) system designed for situational awareness on and off the battlefield. It detects camouflaged positions and equipment, weapons storage, and supports maritime surveillance. The system delivers reliable intelligence data in inclement weather and during night-time operations.

BEYOND TRADITIONAL ISR

Traditional ISR is slow and costly, often reliant on satellites or large, strategic platforms. Sahara changes this by delivering affordable, on-demand radar intelligence at the tactical level. Portable and unit-ready, it puts advanced sensing once reserved for national assets directly into the hands of frontline forces.

SURVEILLANCE AND IMAGING

Sahara delivers clear, actionable SAR intelligence for situational awareness. Its advanced radar processing enables operators to detect man-made structures and activity through amplitude change detection and multi-temporal coherence.

ALL-WEATHER, DAY AND NIGHT

Sahara is built to operate reliably in challenging conditions, delivering radar intelligence day or night and in environments where traditional sensors are limited.

UAV INTEGRATION

Focusing on size, weight, and power efficiency, Sahara is specifically engineered to be integrated into Group 2 UAVs and above, enabling seamless deployment across both existing platforms and future systems.
