Infrared guidance technology is an important missile guidance method in the modern military field. It uses infrared tracking and measurement technology to control and guide missiles to accurately hit the target. This technology mainly serves the passive homing guidance system, and its core components include infrared seekers, computers, and actuators. As a tracking and measuring device, the infrared seeker consists of a cutting disc wheel, an infrared detector, and an optical system. It is mainly used to detect and collect thermal radiation, and then encode the spatial position of the target, and output a pulse sequence containing the target's spatial direction information after photoelectric conversion. These pulse sequences are further output to the torque of the seeker and drive the optical axis of the seeker to track the target. The performance of the seeker directly affects the tracking capability of the missile.
Importance of Infrared Guided Missile Magnets
In infrared guidance systems, the seeker gyro rotor is the core component of the entire seeker. To achieve high-precision guidance, the seeker gyro rotor needs to have low power consumption, high accuracy, and stability. Therefore, magnetic levitation rotor gyros are widely used in the design of seeker gyro rotors. The essence of magnetic levitation is to balance the weight of suspension and load through the magnetic force generated by an adjustable magnetic field. As a provider of the magnetic field, the infrared-guided missile magnet, also known as the primary mirror magnet, will directly affect the quality of the seeker through its magnetic properties. The primary mirror magnet integrates the optical components, gyro rotors, and magnets, so the magnet needs to have sufficient strength, dynamic imbalance, and optical mirror quality, as well as a superior sinusoidal waveform.
Types and Characteristics of Magnets
In the field of AlNiCo magnets, infrared-guided missile magnets have always been regarded as the jewel in the crown. AlNiCo magnets are well known for their excellent magnetic properties and stability, making them very suitable for use in high-precision guidance systems. In addition, NdFeB magnets are also widely used in missile guidance systems due to their high magnetic energy product and corrosion resistance.
Technical Challenges and Innovations
As technology develops, the requirements for infrared-guided missile magnets are also increasing. Magnets need to maintain stability under extreme temperature and pressure conditions while also having sufficient strength and precision. To meet these requirements, researchers are constantly exploring new materials and manufacturing technologies to improve the performance of magnets.
Conclusion
Infrared-guided missile magnets are an indispensable part of modern missile guidance systems. As technology continues to advance, the performance requirements for magnets are also increasing. Through continuous research and innovation, we can expect that infrared-guided missile magnets will be more efficient and reliable in the future, providing more precise guidance capabilities for missile guidance systems.
