Which type of seeker is most likely to be affected by weather conditions?

The electro-optical seeker is most likely to be affected by weather conditions due to its reliance on visible light and infrared signals to acquire and track targets. Weather phenomena such as rain, fog, snow, or clouds can impede visibility and reduce the effectiveness of an electro-optical system. This can result in diminished target detection and tracking capabilities, as these seekers depend heavily on clear, unobstructed optical paths to gather data.

In contrast, active seekers generate their own signals and bounce them off targets to determine their location, making them less sensitive to ambient weather conditions. Passive seekers rely on detecting emissions from targets, which may also be less directly impacted by weather. Semi-active seekers typically require an external illumination source but may still be functional in various weather conditions. Therefore, while all seeker types can experience some level of impact from weather, the electro-optical seeker is distinctly more vulnerable due to its reliance on visual and infrared light.
