A Study on the Development of Seeker Systems of Guided Missiles

As defense science and technology advance, weapon systems are becoming faster, more agile, and equipped with stealth capabilities. Consequently, the importance of precise detection and tracking capabilities in the seeker systems of guided missiles for future battlefields is increasing. Because the development of the seeker systems of guided missiles requires a high level of technology and involves significant time and cost in research and development, countries advanced in defense technology are leading in related technologies. In the Republic of Korea, various guided missiles, such as anti-air and anti-ship missiles, have been independently developed and the related technologies are maturing. However, the development status of leading countries should be analyzed to identify any technological gaps in the capabilities of our seeker system against potential threats. In this paper, we analyze the development status of foreign seeker systems that primarily use RF, IIR, SAL, and multi-mode sensors, as well as the domestic development status of seeker systems. Furthermore, we propose developmental directions for the necessary technologies for future seeker systems of guided missiles.
