A system detects, identifies, and optically tracks a jammer by calculating position and velocity information associated with the jammer based on jamming signals received at one or more antennas, and utilizing the position and velocity information to control one or more cameras. The cameras capture a series of images that include the calculated location, the expected movement of the jammer, or both. The system analyzes the images to extract motion information associated with one or more objects identified in the images. The system utilizes the calculated position and velocity information and the extracted motion information to determine which of the identified object in the images is the jammer. Further, the jammer motion information extracted from the images may be utilized to update the calculated position and velocity information associated with the jammer, to improve the overall accuracy of the tracking of the jammer.
