Synthetic Aperture Radar

Synthetic Aperture Radar (SAR) produces high resolution images and is a payload technology that needs to be attached to a moving platform, like a satellite or aircraft. The forward motion of the platform stimulates the receiving capabilities of a larger antenna (for greater range), while the SAR sends successive radar pulses to the ground. The radar pulses bounce back from the target to the SAR in the form of echoes. SAR images are then generated from a combination of these echoes. SAR is great for maritime surveillance because it can operate regardless of cloud cover, bad weather, or darkness. It is multi-use and applicable to non‐cooperative ship detection, as well as detecting oil slicks or other pollutants.
