Imaging modes

Dwell modes

Immediately recognize objects – take your security applications to new heights with Dwell.

The game changer

ICEYE Dwell mode imagery is a world-first capability that lets you see and understand movement, classify objects, and make faster and better decisions with more confidence than ever before. ICEYE Dwell modes include Color Sub-Aperture Images (CSI) and SAR video.

ICEYE first introduced Dwell mode in May 2023, followed by Dwell Fine in March 2024. Dwell Precise, the industry's highest-fidelity 25 cm imaging product, was released in October 2024.

Dwell Precise

The industry's highest-fidelity 25 cm imaging product

Dwell Precise combines high-quality data with high resolution. Its 1200 MHz radar bandwidth determines the unique 25 cm resolution.

You can identify smaller objects or targets, such as types of vehicles and military equipment, without the need for additional intelligence sources.

Dwell modes offer unparalleled information density and highly reduced speckle, which means every detail in an image appears crystal clear. This Dwell Precise mode image of Rotterdam, The Netherlands, is an example of the vast amount of detail available in a single image.

“As soon as a satellite flies over, we see this bright object on the battlefield or on the airfield, and we can very quickly categorize exactly what that is.”

Designed for security applications

With ICEYE Dwell modes, you can make better and faster decisions with more confidence than ever before. Click through the Dwell mode image examples below and see the clarity.

Dwell mode lets you classify vessels stationed in ports with more confidence. Distinguish between specific generations of vessels identifying the design and equipment differences. This is a detail of vessels in a port acquired by ICEYE Dwell Precise mode image.

Details such as this transmission tower are clearly visible in Dwell Precise imagery.

1. Aircraft_reduced

Detect and classify aircraft. See the clear shape of their fuselage, wings, stabilizers, and engines. Distinguish between various aircraft types with more confidence than ever before. This is an ICEYE Dwell mode image of the C-17 Globemaster transport aircraft.

2. Helicopters_reduced

Helicopters can be more easily identified with Dwell mode than with conventional Spot collections. Dwell mode's long imaging time allows many aspect-angle-dependent reflections to be observed in the same image, which makes the object look more complete. This is an ICEYE SAR image of various helicopters stationed on an airfield.

4. Power Lines_reduced

Dwell mode allows you to see narrow objects like power lines and antennas, which cannot be seen in other Spot collections. The long imaging time allows many aspect-angle-dependent reflections to be observed in the same image, which makes the object look more complete. This is an ICEYE Dwell mode CSI product (Color Sub-aperture Image) showcasing its ability to see objects as narrow as individual power lines.

5. infrastructure damage_reduced

Dwell mode's CSI product (Color Sub-aperture Image) allows you to better understand infrastructure damage. In this image, you can see a damaged bridge and explosion craters.

6. Objects in forests_reduced

Although X-band SAR cannot penetrate the forest canopy, Dwell mode's very long illumination time lets you detect objects hidden in forested areas. Because images in Dwell mode are taken from a much wider range of angles, you can detect objects through gaps in the trees and foliage.

Dive deeper into the details of moving objects and understand the nature of the motion in your location. With Dwell mode, you can analyze several sub-aperture images taken during a single collection – either separately or as a video preview made up of an image stack.

Human-made objects are indicated with colors to distinguish them from natural features.

With Dwell modes, human-made structures like armor, trucks, and vehicles are highlighted in colors and stand out from natural objects, which appear as gray. This helps analysts immediately see where to focus their attention. Dwell's long capture time from a wide range of angles means you're also able to see objects between branches and trees, an unprecedented capacity that only ICEYE can deliver.

Identify the movement of objects in your area of interest

Analyze a 25-second motion sequence to identify the speed, velocity and heading of moving objects.

Dwell modes' unprecedented 25-second collection time enables us to turn an image stack into a video that gives you immediate insights into the movement of objects in your area of interest. Because Dwell mode videos are made up of individual, high-fidelity, high-acuity images, moving objects appear clear. You can identify the speed, velocity, and direction of vessels in the open ocean, vehicles on land, and much more.
