Dubai, UAE – ICEYE, the global leader in radar satellite persistent monitoring of the planet and an expert in natural catastrophe solutions, today announced a new imaging mode known as Dwell. With Dwell, ICEYE synthetic aperture radar (SAR) satellites remain focused on a specific point on the ground for an extended collection time. This unique long-duration imaging mode allows ICEYE satellites to capture significantly more information about the imaging target, creating a powerful new capability for imagery users. For example, Dwell can be used to determine the heading and speed of moving vehicles, and under some circumstances, Dwell can even enable the discovery of human-made objects that would otherwise remain hidden under tree canopy. The Dwell product is unique in commercial remote sensing and will transform how customers with demanding mission requirements exploit SAR imagery.

The Dwell image product is created from a 25-second collection of the imaging target, in contrast to the 10-second duration of a traditional high-resolution ICEYE Spot image. This longer-duration collection provides new information about activity on the ground while also improving the image fidelity over a traditional SAR image. The result is a powerful new imaging capability that will expand the use of SAR for critical applications. Importantly, when combined with ICEYE’s day/night all-weather imaging capability and tactical responsiveness, Dwell provides an imagery capability that is superior to electro-optical collections.

The Dwell product is a bundle with three components:

  1. High-fidelity SAR image. A common feature in high-resolution SAR images is speckle, which is the result of the specific SAR collection geometry and gives SAR imagery a noise-like appearance.  The extended collection time for a Dwell image enables a significantly larger synthetic aperture angle and produces pixels with an along-track resolution of 5 cm. Standard processing combines pixels together, a process called ‘multi-looking’, which significantly reduces the speckle artifacts. The result is a high-fidelity image with superior interpretability.
  2. Color subaperture image. A Dwell collection is particularly efficient at distinguishing human-made features, such as vehicles and buildings, from natural backgrounds such as tree canopy and vegetation. The color subaperture image preferentially distinguishes human-made features, allowing analysts to quickly find objects and features of interest among natural backgrounds.
  3. Video. The video is built from the multiple sub-images that comprise a Dwell collection. The video product enables determination of vehicle heading and speed during the 25-second collection, and provides additional context about activities and patterns of behavior.

"Dwell mode is ideal for customers who need to extract more information from our radar imagery, including movement and direction," said John Cartwright, Head of Data Product at ICEYE. "In the long term, the research community, scientists, the SAR community, and most importantly, our customers with demanding missions will benefit from this latest ICEYE innovation. This product is another element in using remote sensing to better understand and characterize what is happening and changing on the ground in all lighting and weather conditions," he said. 

Dwell expands the powerful portfolio of high-tempo, day/night, all-weather imaging capabilities enabled by the ICEYE constellation. Today ICEYE offers a wide-area collection mode called Scan for large area search; an intermediate, higher-resolution mode called Strip for higher-resolution mapping and search, and highest-resolution Spot and Spot Extended Area for high-confidence monitoring and mapping applications. With the introduction of Dwell, users can now unlock new insights about their areas of interest, doing so with capabilities unique to the commercial SAR market.


ICEYE delivers unmatched persistent monitoring capabilities for any location on earth. Owning the world's largest synthetic-aperture radar satellite constellation, the company enables objective, data-driven decisions for its customers in sectors such as insurance, natural catastrophe response and recovery, security, maritime monitoring, and finance. ICEYE's data can be collected day or night and even through cloud cover.

For more information on ICEYE SAR imaging modes: 


Spot mode enables the finest resolution and largest available scene size for detailed monitoring, delivered up to multiple times per day and in any weather. Use Spot mode for object identification and highly detailed change detection in a 5 km x 5 km imaging footprint. The Spot Extended Area variant expands the imaging footprint from 5 km x 5 km to 15 km x 15 km.  ICEYE continues to make enhancements to Spot Mode, with more variants to come.


Strip mode is perfect for detecting changes to vast sea and land areas in a 30 km x 50 km footprint. Use Strip mode to see and respond to natural disasters and illegal activities such as deforestation and to persistently monitor borders, coastal areas or any location of interest.


Scan mode can cover an area of up to 100 km by 100 km. Scan mode is particularly effective for acquiring wide coverage imagery for maritime use cases, where national security authorities and maritime safety officials need persistent visibility.
