스텔라레스큐 – Portable SAR

In fire situations, the interior of buildings is often obscured by smoke and debris, making it difficult for firefighters to pinpoint the location of trapped individuals.

Previously, search efforts relied on thermal cameras or visual inspection, but thermal imaging can become saturated due to flame temperatures, and the discovery of motionless or injured victims can be delayed. Furthermore, entering the building to visually confirm conditions exposes firefighters to danger due to the lack of pre-entry search information.

In this context, the need for new technologies to accelerate indoor search operations and ensure safety has emerged.

The key differentiator is the miniaturization of satellite radar technology for ground use, creating an ultra-wideband radar sensor that detects objects behind walls without GPS or line of sight.

The device, weighing approximately 900g, incorporates a flat-panel array antenna and FPGA-based signal processing to map the internal structure of buildings in real-time and analyze even subtle bio-signals (breathing, limb movements) using AI.

Unaffected by smoke, darkness, or obstacles, the device can be activated outside the building before rescuers enter, displaying the location and movement of people inside as an augmented reality map. It offers superior detection accuracy and range compared to existing thermal imaging and can be mounted on a drone for remote searches in difficult-to-access areas.

In short,"A Firefighting Radar That Sees the Unseen"which is differentiated by shortening the search golden time at the fire scene and reducing the risk exposure of firefighters.

Fire departments and disaster relief agencies (B2G)are the primary customers, with the equipment potentially being distributed to front-line fire brigades. It can also be used in urban warfare hostage rescue operations by military units and hostage rescue operations by police special forces, etc.Special Forces (B2B/B2G)It is also available in.

Building safety companies or large building management teams may also consider adopting it for disaster preparedness. Given the price and expertise required, it is not a product for individual purchase, but rather one that is purchased with public funds or corporate safety investments and used by firefighters in the field.

This equipment could have universal demand from fire departments and disaster response agencies worldwide.

In terms of regulations, there are issues such as radar frequency usage permits, but there are no major restrictions if frequency bands are adjusted to obtain certifications in each country.

Technically, it can be expanded to various scenarios beyond fire searches, such as searching for survivors in earthquake and other disaster collapse sites, and rescuing people from ship fires by the Navy. However, if classified for military use, caution should be exercised regarding export controls, but since it is basically positioned as a civilian survivor search device, it is expected to be adopted in most countries.

Stellarvision, as a startup, plans to collaborate with governments and fire organizations in each country to promote entry into the international market.

Recognized for its technology with the CES 2026 Innovation Award in the Drones/Robotics category.

Experts praised it, saying, *"Space technology has been applied to firefighting,"* and expectations for on-site effectiveness are high. In particular, the AI-based detection accuracy received favorable reviews in demonstrations, and there was a positive response that it is *"a solution that will secure the golden hour for life saving."

However, market validation is in its early stages, and it is also pointed out that the long adoption cycle and budget acquisition issues, which are characteristic of public procurement, may be variables in the speed of commercialization. Overall, the evaluation at CES is positive, but it is assessed that additional field testing and trust building are needed before it can become standard equipment in fire fighting sites around the world.
