红外制导技术 is a military technology which uses infrared tracking and measurement to control and guide missiles to the target.是一项军事技术，它使用红外跟踪和测量来控制导弹并将其引导到目标。 Infrared guided technology is mostly utilized by the passive homing guidance.被动制导系统主要利用红外制导技术。 Infrared guided system consists of the infrared seeker, computer, and actuator.红外引导系统由红外搜寻器，计算机和执行器组成。 As the tracking and measurement apparatus, infrared seeker makes up of the chopper wheel, infrared detector, and optical system.作为跟踪和测量设备，红外搜寻器由斩波轮，红外检测器和光学系统组成。 Infrared seeker is mainly used to detect and collect heat radiation, then encoding the position of the target in space after modulation, thus output pulse sequence which includes target's spatial direction information after photoelectric conversion.红外导引器主要用于检测和收集热辐射，然后在调制后对目标在空间中的位置进行编码，从而输出包含光电转换后目标的空间方向信息的脉冲序列。 The pulse sequence will further output to the torquer of seeker and drive seeker's optic axis to track the target.脉冲序列将进一步输出到搜索器的扭矩器，并驱动搜索器的光轴以跟踪目标。 The performance of seeker is directly reflected in the capacity of missile's traceability.导引头的性能直接反映在导弹的可追踪能力上。 In fact, infrared guided missile magnets have long been considered as the bright pearl of the crown in实际上，红外制导导弹磁铁长期以来一直被视为皇冠上的明珠。 铝镍钴 区。
The seeker gyrorotor is the core component of the whole seeker.寻星陀螺仪是整个寻星器的核心部件。 High-accuracy guidance system requires its seeker gyrorotor has low power consumption, high accuracy, and stability, therefore, magnetic support rotor gyro has been widely applied to the design of seeker gyrorotor.高精度制导系统要求其导引陀螺仪具有低功耗，高精度和稳定的特点，因此，磁支撑转子陀螺仪已被广泛应用于导引陀螺仪的设计中。 The essence of magnetic support is the weight of suspension and load it suffered can be balanced by ponderomotive force generated by adjustable magnetic field.磁性支撑的本质是悬架的重量和可承受的负载可以通过可调磁场产生的磁动力来平衡。 As the provider of magnetic field, infrared guided missile magnets which also known as primary mirror magnet, its magnetic properties will directly impact the quality of the seeker.作为磁场的提供者，红外制导导弹磁体也称为主镜磁体，其磁性能将直接影响搜寻器的质量。 Primary mirror magnet integrates optical part, gyrorotor and magnet together, then magnets should have sufficient strength, dynamic unbalance, and optical mirror quality besides superior sine wave.主镜磁体将光学部件，陀螺仪和磁体集成在一起，因此，除了优异的正弦波，磁体还应具有足够的强度，动态失衡和光学镜质量。
