Analyst Note:
This image shows the three lenses that form the new version of the Kh-101 Digital Scene Matching Area Correlator (DSMAC) system. (The older version only had a single lens.) DSMAC systems take digital images of the ground as the missile passes overhead, and then compare those images to pre-captured images stored in the onboard memory. The DSMAC corrects the flight path as needed based on differences between the two sets of images. (ARES)
