Which type of seeker uses imaging or a built-in camera for guidance?

An electro-optical seeker utilizes imaging technology or a built-in camera for guidance, making it essential for precise targeting and tracking. This type of seeker can detect and track specific heat signatures or visual images, allowing for effective engagement with targets in various environments, including day and night operations. The imaging capability enables the seeker to distinguish between multiple potential targets, enhancing its selectivity and effectiveness.

In contrast, active seekers generate their own signals to locate targets, relying on reflected signals, while passive seekers depend on external sources of energy, such as heat or radar, to detect targets. Semi-active seekers require illumination from an external source, usually to guide a missile to a target. These differences in capability and function highlight the unique role of electro-optical seekers in modern maritime warfare.
