Satellite imagery / Radar (SAR)

Radar (SAR) satellite imagery
through cloud, day or night.

Synthetic aperture radar sends its own microwave signal, so it can image the ground through cloud and in darkness. Use it to map floods, detect changes and measure ground motion with InSAR, from free Sentinel-1 data to commercial high-resolution radar.

Availability, minimum order area, price and license depend on the location and the request. We confirm them in your quote; submitting an enquiry does not place an order.

What you can order

Radar data you can order.

Sentinel-1: free radar
Open radar images from the European Copernicus program, with regular repeat coverage of most land areas. A good start for floods and change.
Commercial high-resolution SAR
Operators such as ICEYE, Capella and Umbra sell radar images below 1 m resolution in their finest modes, from the archive or as a new capture.
InSAR ground motion
Repeated radar images compared to measure ground movement of millimetres to centimeters over time, for subsidence and structures.
Change and flood products
Processed maps of water extent or change between two dates, for teams that want an answer rather than raw radar.

Common uses

When radar is the right choice.

Floods under cloud

Map water extent during storms, when optical satellites see only cloud.

Subsidence and structures

Screen buildings, roads and pipelines for ground movement with InSAR.

Change in cloudy regions

Detect clearing, construction or damage in places where clear optical images are rare.

Night-time and urgent captures

Get an image regardless of daylight when timing matters.

How ordering works

From your request
to files you can use.

  1. 01

    Tell us the place and the need

    Share the location or boundary, the dates and what you want to see or measure. A rough description is enough to start.

  2. 02

    Review the options and the quote

    We check suitable sources and show the capture dates, coverage, resolution, license and complete price before you commit.

  3. 03

    Receive the data

    Get the files with their metadata and license, ready for your own tools, or ask us to quote an analysis.

Before you buy, check

  • Radar images look different from photos: speckle, shadows and layover take practice to read.
  • Polarization, incidence angle and orbit direction affect comparisons between dates.
  • InSAR needs a stack of repeated images and stable surfaces.
  • Raw radar often needs processing before it answers a question.

Questions

Radar (SAR) imagery: your questions.

Can radar see through clouds?

Yes. Radar uses microwaves that pass through cloud and does not need sunlight, which makes it reliable during storms and at night.

What is InSAR?

Interferometric SAR compares the radar signal between dates to measure small ground movements. It works best on stable surfaces such as buildings and roads, with many repeated images.

Do I need specialist skills to use SAR?

Raw radar takes practice to interpret. You can order processed flood, change or ground-motion products instead, or ask for an analysis alongside the data.
