Abstract : Cryogenic refrigerators, paired with external detectors, are key products urgently needed for military modernization and high-tech development. Domestic research and development technology has approached international advanced levels, and key technologies related to miniaturization, low vibration, long lifespan, fine square enameled wire fabrication, gap sealing, and electromagnetic interference elimination have been basically mastered. This article lists the main technical performance of a linear motor resonant compressor that has been developed. It is hoped that all parties involved—management, users, research and development, and production—will work together to apply, improve, reapply, and improve again, thereby realizing the industrialization of cryogenic refrigerators in China. Keywords : Cryogenic refrigerator; Linear motor; Compressor 1 Introduction The Gulf War, the Kosovo War, and the Bosnian War demonstrated the power of modern weapons, especially the astonishing accuracy of missiles. The secret lies in the application of infrared imaging guidance, that is, using an infrared missile positioner to receive the infrared radiation of the target, image it on the focal plane, and after processing, provide the target's azimuth signal to the tracking system. This is equivalent to giving the missile a bright eye. Infrared imaging guidance utilizes the thermal radiation difference between the target and the background to form an image of the target and its surroundings, achieving automatic guidance—a precision guidance method with strong anti-jamming capabilities and representing a major development direction in guidance technology. Infrared imaging systems have demonstrated significant advantages in target search and tracking, aiming, and infrared guidance during nighttime or adverse weather conditions. Infrared focal plane array infrared imaging systems have been widely used in the military, including in spaceborne early warning systems, low-altitude air defense, pre-emptive reconnaissance, search and tracking, border defense, security, nighttime navigation, missile guidance, real-time precision strikes, post-strike reconnaissance and estimation, and target search in complex backgrounds, changing sea and sky conditions, and complete darkness. Strong night vision capabilities provide greater initiative in modern warfare and are a hallmark of national defense modernization.
