| Abstract:The infrared seeker is the core component of the weapon guidance system for identifying and tracking targets, and it determines whether the guided missile can successfully hit the target accurately. In modern warfare, the combat conditions are complex and variable, with factors such as clouds, fog, point source decoys, laser suppression, camouflage, and multiple wave attacks that can interfere with the infrared guidance head in achieving the task of identifying and continuously tracking the target's features. This paper summarizes the various interference factors on the battlefield, analyzes the interference mechanisms and their impact on the performance of infrared guidance heads, and introduces the main anti-interference technologies currently in use. It provides a detailed analysis of the design principles and operation flow of these technologies, and shows the anti-interference effects of infrared guidance heads in various application scenarios, which has some reference value for the formulation of anti-interference strategies for infrared guidance heads. |
