What is SAR?

Synthetic Aperture Radar (“SAR”) is a form of radar used to create 2-D images or 3-D reconstructions of objects.

  • Provides high-resolution, day-and-night and weather-independent images for a multitude of applications ranging from geoscience and climate change research, environmental and Earth system monitoring, 2-D and 3-D mapping, change detection, 4-D mapping (space and time), security-related applications up to planetary exploration.
  • The SAR satellite sends microwave pulses to Earth. The pulses return back to the satellite and the sensor makes an image from the returned echoes. Similar to how bats use soundwaves to navigate. SAR systems uses multiple passes to compare how an area has changed over time. SAR systems isolate and track moving objects, such as people and vehicles.
  • Traditional optical satellites can only measure reflected solar light and can only function during daytime and are restricted by clouds. SAR can penetrate through clouds, vegetation, and other conditions and can operate in day or night conditions.
  • Recent advancements in engineering, manufacturing, and the way SAR data is collected and processed have decreased the size, weight, power consumption, and cost of SAR systems. At the same time, the capabilities of SAR have increased so that data can be sent to the ground in virtually real time with very important and practical uses.
