The Application of Laser Technology in Military-paper代写

留学生paper代写精选范文：“The Application of Laser Technology in Military”，这篇论文讨论了激光技术在军事上的应用。激光被称为20世纪新四大发明之一，对人类社会有着很大的影响。经过了多年的发展，激光技术已经逐渐发展成熟，特别是在军事上的应用，都受到了世界各国的重视。激光技术在军事上的应用主要有激光制导武器、激光通信、激光干扰和激光雷达等，这些都有可能成为未来军事技术最活跃的一个领域。

Laser technology is the beginning of the 1960s developed a high-tech, after 40 years of development, from the principle of the mechanism of laser technology, experimental methods the manufacturing process have been gradually mature. Laser with high brightness, high directivity, good color, good coherence and other important characteristics, widely used in the military field, by the major military powers of attention, the future of military technology is expected to become one of the most active areas.

Laser-guided weapons with high precision strike, target acquisition and flexible, low-cost guidance system, anti-jamming performance, simple operation. Laser-guided laser is a laser target designator shot on target, the missile target laser detector receives the reflected laser back, track and missile guidance control target, there are a large number of laser-guided weapons armed forces.

Rounds of laser-guided missile can simultaneously target, namely the laser signal encoded with a number of indicators were controlled several missiles, while countering incoming targets, improve combat effectiveness. To improve the laser-guided-weather capability, all countries in the development of advanced laser target designators, day and night to ensure operational use. At present the system is still semi-active laser-guided homing guidance and beam guidance, developing a high-performance laser pointer and target acquisition and tracking systems to improve anti-jamming capability and survivability of the weapon system.

Laser communication is the use of military laser transfer information troops. Since the laser communication with large capacity, strong anti-interference ability, good security performance, lightweight structures, equipment and economic characteristics, it is gradually replacing electromagnetic communication, become the main means of communication of military operations. Laser communications units include atmospheric laser communications, optical communications laser, laser communication underwater, space laser communications. Currently, the national army are actively developing laser communications and laser communications troops have set up. The most common is laser communication atmosphere, because of its short wavelength, divergence angle small, the antenna can be made small, mainly used between islands, between the ship, between the border posts, and missile launch site and command centers secure communication between the short distance, the communication susceptible to atmospheric but weather, terrain, terrain, etc., need to be relayed through a satellite or an aircraft. Since the space is less influential carrier communication transmitting light of many factors, such communication between the space vector commonly used in communication.

For the Navy, a laser is particularly important for submarine communication, water penetrates the minimum attenuation blue or green wavelength of 0.47 ~ 0.54mm deep blue light propagation through 100m, the loss is only 1/100 of other wavelengths, Lan Lvguang penetration in seawater up to 600m or more. The world's major powers in efforts to improve the laser detector detection performance, the development of laser technology to capture tracking signal beam to improve the ability of the laser communications.

Principle as laser ranging as microwave radar, laser rangefinder, but compared with the normal distance, having a distal, accurate, fast, interference, no blind spot and so on. It is the use of this feature, accurately measure the distance between the Moon and Earth, the laser ranging has been widely used in conventional weapons, the optical ranging substituted general trend.

Lidar and microwave radar is similar to a region scanned with a narrow laser beam, and obtain the radar FIG. With the development of related technologies and devices, laser radar and take advantage of high precision imaging, ranging accuracy which centimeter-level or even millimeter, nearly 100 times higher than the microwave radar; precision measuring angular velocity, theoretically higher than the microwave radar more than a hundred million times, now do 1,000 to 10,000 times higher.

In just a few decades, laser weapons have become the weapons kind of high hit rate and good anti-jamming capability, increasingly favored by countries, but also Qiang Lie stimulate the development and application of laser interference technology. Laser interference is to use a laser jamming weapons, equipment and devices, laser interference detection, laser communications, laser command, laser control system of the enemy, so they cannot play the power, and protect one's own against enemy jamming. Conventional laser interference can be divided into passive and active jamming interference types. Passive jamming laser does not emit light itself, using equipment, such as smoke, balloons, camouflage, and the like, the laser light scattering, absorption, laser interference signal so as to weaken the effectiveness of the enemy's weapons systems and optoelectronic devices. Laser interference is to use one's own active optoelectronic devices emit laser or forwarded to deceive or suppress enemy weapons systems and optoelectronic devices.

In the future battlefield, the troops will work with laser jamming electronic warfare troops together, become electronic fight with the enemy indispensable combat forces. Laser interference is an integral part of the electro-optical countermeasure technology is essential to modern high-tech warfare.
