Guidance system Advantages Disadvantages Jammings Typical application TV seeker High resolution, clear target image, which is conducive to the identification of true and false targets; passive detection, good concealment, not easy to expose itself Inability to work at night or in poor visibility Not affected by electromagnetic jamming, but susceptible to interference from battlefield occlusion, smoke, explosives, snow reflection and backlighting AGM-130 AGM-142 Kh-59 Infrared seeker It can work day and night; the advantages of strong smoke penetration, high resolution, high sensitivity, high information update rate, etc.; suitable for high-speed maneuvering small targets, complex ground objects background moving targets or hidden targets; target recognition ability, targeting point recognition options strong ability and anti-jamming ability; passive search method, good attack concealment The detector has a long refrigeration time. If you carry a gas cylinder, the guarantee requirements are high and the cost is relatively high Although it is not affected by radio jamming, it may be interfered by infrared decoys, infrared smoke screens, infrared jammers, infrared directional, etc., clouds reflected sunlight, infrared and other heat sources to lure, deviate and lose the target SLAM-ER JASSM JSOW AIM-9X ASRAAM LRASM Laser semi-active seeker High guidance accuracy, strong anti-jamming ability of laser coding, can be combined with TV, infrared or radar, etc. to form a composite guidance feature, the guidance system is small in size, light in weight, and relatively cost-effective It is susceptible to weather conditions and cannot be used all-weather; before the missile hits the target, the laser beam must always illuminate the target, and the aircraft or other platforms can be easily detected by the enemy and attacked. Affected by jamming such as high repetition frequency laser, laser suppression, laser blinding (dazzling) jamming, laser active deception, etc. PAVEWAY PYROS AGM-114 APKWSⅡ TV/infrared composite seeker TV and infrared can work independently at the same time, time-sharing and shifting work in sections, giving full play to their respective advantages and restraining their respective disadvantages. Added the capabilities and advantages of pixel-level fusion feature extraction, feature-level fusion target recognition and tracking, decision -level fusion control SPIKE MMP Uncooled infrared/laser semi-active composite seeker Uncooled infrared and laser semi-active can work independently at the same time, time-sharing and shifting work in sections, giving full play to their respective advantages and restraining their respective disadvantages. Can significantly expand the working distance of uncooled infrared, and has certain information fusion control capabilities and advantages SDBⅡ PAM TV/uncooled infrared/laser semi-active composite seeker Combining the advantages and disadvantages of TV, uncooled infrared and laser semi-active. The overall system is relatively complex, difficult to design, verify and manufacture, and costly. It has pixel-level fusion feature extraction, feature-level fusion target recognition and tracking, decision-level integrated information fusion control capabilities, and strong comprehensive anti-jamming capabilities SPIKE NLOS
