Synthetic Aperture Radar (SAR) is a groundbreaking technology that’s reshaping industries and delivering critical Earth insights. Yet, like any innovative tool, it can come with misconceptions. Let’s debunk some of the most common SAR myths and uncover the facts.
Myth 1: SAR Exposure is Harmful
Reality: When people hear about radar technology, some imagine beams of energy harmful to living organisms. This misconception often stems from confusion with ionizing radiation, such as X-rays or gamma rays, which can damage biological tissue. SAR, however, operates using non-ionizing electromagnetic waves, similar to those used in Wi-Fi or radio communications.
These waves interact with surfaces to provide imagery but pose no threat to health. Regulatory bodies ensure SAR systems operate well within safety limits, and SAR satellites, like those from Capella Space, prioritize responsible design and operation. So rest easy—SAR is safe.
Myth 2: SAR Can See Through Buildings
Reality: This myth likely stems from SAR’s remarkable ability to penetrate clouds, smoke, and vegetation. However, SAR cannot see through solid structures like walls or roofs. Instead, it interacts with surfaces, bouncing radar waves back to create detailed imagery of exterior features like building outlines, roads, or landscapes.
SAR’s strength lies in monitoring infrastructure and environmental changes, not invading personal privacy. If you’re looking for tech to peer inside buildings, SAR isn’t it—and that’s intentional.
Myth 3: SAR is Too Complex for Everyday Use
Reality: SAR’s technical sophistication can be intimidating, but accessing its benefits is easier than ever. Capella Space has revolutionized how users interact with SAR data, offering automated tasking, user-friendly platforms, and near-real-time data delivery.
It's easier than ever before to harness SAR’s power—whether you’re managing a supply chain, responding to a natural disaster, or conducting infrastructure assessments, SAR data is more accessible and actionable at a commercial scale.
Myth 4: SAR Data Takes Too Long to Process
Reality: Gone are the days of waiting hours—or even days—for SAR data. In its early days, Modern advancements, however, have changed the game.
Capella Space’s automated tasking and rapid data downlink deliver insights in minutes. Whether monitoring active wildfires or tracking maritime activity, SAR now provides data in near-real-time, making it a critical tool for industries where time is of the essence.

Myth 5: SAR and Optical Satellites Do the Same Thing
Reality: Some think SAR and optical satellites are interchangeable, but they are fundamentally different tools with complementary strengths. Optical satellites provide imagery akin to what you see with your eyes, capturing visual information like color and texture.
SAR, on the other hand, excels at detecting structural details, changes in elevation, or surface shifts—even through clouds or darkness. Together, they create a fuller, more detailed picture, enabling smarter decision-making.
