From page 1...
... Conclusion 1-1: Active EO sensing enables measurements not possible with passive EO sensors by exploiting the control of the illumination. Exploiting control of the illumination includes its coherence properties.

From page 2...
... Usually, the light used in active EO sensing has a narrow wavelength band. Interfering narrowband scattered light from different portions of a rough surface creates light and dark areas at the receiver called speckle.

... The second category is only accessible to countries with significant resources. High-performance, specialized active EO sensing devices and systems require significant investment to develop, pose difficult engineering challenges to deploy, and require persistence and a long lead time to field practical systems.
