Original title: application of remote sensing technology in military
Golden Monkey has a pair of eyes, you can identify friend or foe. Strategies for our army in the new wave of reforms to set up support units, is a new combat force to protect national security, is important point of our army's new combat capability, strategy for remote sensing technology is an important part of support units of soft power.
First developed for military applications of remote sensing satellite, later there gradually extend from military proprietary technology to civilian areas. From the available information, used in satellite remote sensing technology, compared to the current military and civilian satellites, has maintained its absolute technological advantage. Application of space remote sensing technology in the military field, including military reconnaissance, missile early warning, weapon guidance systems, military surveying and mapping.
Remote sensing technology used for military reconnaissance, is the most effective, safest, and most reliable means of reconnaissance. According to international practice, distance of 100 km above the Earth's surface into space, does not belong to the country's air space, without fear of reconnaissance activities of persons accused of acts of aggression. Therefore, an important means of space remote sensing technology as a modern military reconnaissance, has a wide detection range, are not affected by geographical conditions, the advantages of finding fast, to obtain using other ways to get military information.
Satellite remote sensing technology and the development of optical fiber communication technology, any open targets in a country well aware can be detected in other countries and satellite observations, remote physical-chemical analysis and information processing technologies, and strengthening the capacity of military intelligence intercepts and the verification of weapons facilities, military sovereignty and national border security are under threat from invisible invasion. Remote sensing photos taken from reconnaissance satellites, could see the aircraft and missile launchers and other military equipment and facilities, can distinguish types of tanks and fighting vehicles, able to identify objects of diameter 0.1-0.3 m. While, on combat regional clock, and full day, and full, and high dynamic of space remote sensing reconnaissance, can quickly, and timely to gets more band, and long phase, and high resolution of remote sensing image information, to understand enemy overall deployment situation, monitored, and track and forecast enemy forces of future action, full master combat target of location distribution, guide precise attack weapons accurate hits target, and effective assessment battlefield damage effect.
With the miniaturization of remote sensing systems, remote sensing technology and weapons to improve weapons intelligence and accuracy, has become one of the trend of remote sensing technology. Remote sensing technology can be used for tactical missiles, artillery shells and bombs, weapon guidance systems, can also be used for missile guidance systems.
Military remote sensing surveying and mapping technology in the military one of the most important applications is to provide military operations military topographic maps and mapping service guarantees for the future digitized battlefield.
After more than 30 years of development, remote sensing technology has penetrated into all areas of our national economy and national defense. Our current military remote sensing satellite "Vanguard" series of reconnaissance satellites, as well as "outpost" series infrared early-warning satellites.
China remote sensing satellite system satellites and technology behind the United States "keyhole" and "Lacrosse" series of remote sensing satellite system, but with the development of China's space industry, remote sensing satellite in China's defense and military operations in the future will increasingly play an important role.

专家析中国侦查预警卫星：数量技术均不如美国|遥感|卫星|技术_新闻资讯
原标题：遥感技术在国防军事上的应用
金猴有一双火眼金睛，能够识别敌我。在我军新一轮改革浪潮中成立的战略支援部队，是维护国家安全的新型作战力量，是我军新质作战能力的重要增长点，其中遥感技术就是战略支援部队软实力的重要组成。
遥感卫星最早就是为了军事应用而研制，后来有一些逐渐从军事专用技术扩展到民用领域。从已掌握的资料来看，在卫星使用的遥感技术上，目前军用卫星与民用卫星相比，依然保持着绝对的技术优势。航天遥感技术在军事方面的应用主要包括军事侦察、导弹预警、武器制导、军事测绘。
遥感技术用于军事侦察，是目前最为有效、最为安全，同时又是最可靠的侦察手段。按照国际惯例，距离地球表面100公里以上的太空，不属于地面国家的领空范围，不必担心侦察卫星的活动被指控为侵略行为。因此，航天遥感技术作为现代军事侦察的重要手段，具有侦察范围广、不受地理条件限制、发现目标快等优点，能获取采用其他途径难以得到的军事情报。
由于卫星遥感技术和光纤通信技术的发展，使一国境内的任何露天目标都能被其他国家侦察得了如指掌；而卫星观测、远程理化分析及信息加工技术，又加强了截获军事情报及核查武器设施的能力，国家的军事主权和边界安全都面临无形侵袭的威胁。从侦察卫星拍摄的遥感照片上，能看清飞机和导弹发射架等军事装备和设施，能分辨坦克和战车的类型，能识别直径为0.1－0.3米的物体。同时，对作战区域全天候、全天时、全方位、高动态的航天遥感侦察，可以迅速、及时地获取多频段、多时相、高分辨率的遥感图像信息，从而了解敌方整体部署情况，监视、跟踪并预测敌方部队的未来行动，全面掌握打击目标的位置分布，引导精确攻击武器准确命中目标，并有效评估战场毁伤效果。
随着遥感系统的小型化，把遥感技术和武器相结合以提高武器智能化水平与命中精度，已成为遥感技术发展的趋势之一。遥感技术既可用于战术导弹、炮弹和炸弹等武器的制导系统，也可用于战略导弹的制导系统。
军事遥感测绘技术在军事上的一个重要应用，就是为军事行动提供军用地形图以及为未来数字化战场做好测绘勤务保障。
经过30多年的发展，遥感技术已广泛渗透到我国民经济及国防建设的各个领域。我国现有的军用遥感卫星有“尖兵”系列侦察卫星以及“前哨”系列红外预警卫星。
中国的遥感卫星系统整体卫星数量和技术水平虽然落后于美国的“锁眼”“长曲棍球”系列遥感卫星系统，但随着中国航天事业的高速发展，遥感卫星在中国的国防领域以及未来的军事行动中将越来越扮演着重要的角色。（来源：科技日报 作者刘恺健 单位：北京航空航天大学）
