攻击卫星的方法

攻击卫星的方法: 
Against the satellite methods:      

1.    直接摧毁地面作站:     
1. Directly destroy the ground for station:  

利用导弹,爆炸装置直接对地面站进行永久性破坏攻击。  
Using missile, explosive devices to a station directly for permanent damage attack.      

接收、处理、存档、分发各类地球对地观测卫星数据,为全国服务,同时开展卫星遥感影像数据接收与处理以及相关技术的研究。      
Receiving, processing, and archive, distribution of all kinds of earth observation satellite data, for national service, at the same time develop satellite remote sensing image data receiving and processing and related technology research.     

经过多年发展,地面站已形成了以北京本部数据处理与运行管理为核心,北京接收站(位于密云)为数据接收点的运行格局。  
After years of development, a station has formed to the Beijing data processing and operation management as the core, Beijing station (located at the miyun) for the data of operation method-the peak-trough pattern.      

接收站内配备大型接收天线2部、中小型接收天线2部及相关的各种卫星数据接收、记录设施多套,具备接收国内外15颗遥感卫星数据的能力,目前全天候运行性接收9颗卫星数据,初步实现了一站多星,多种分辨率和全天候、全天时、准实时。      
In the terminal with large receiving antenna 2 department, small and medium-sized receiving antenna 2 department and all kinds of relevant satellite data receiving, records sets of facilities, have receive 15 of the ability of satellite remote sensing data, currently running sex receive 9 all-weather satellite data, primarily achieved more than a station star, a variety of resolution and 24-hour, when all day, quasi real time.      

同时,北京总部针对不同卫星形成了较为完善的运行管理系统、数据处理系统、数据管理系统、数据检索与技术服务系统等。  
At the same time, Beijing headquarters in different satellite form the relatively perfect operation management system, data processing system, data management system, data retrieval and technical service system, etc.   

具备日处理各类卫星影像数据100多景的能力。  
Have th handling all types of satellite image data more than 100 the landscape of the ability.

激光武器攻击    
Laser weapon attack:   

反卫星武器也层出不穷。     
The anti-satellite weapons also emerge in endlessly. 

目前除了反卫星导弹之外激光武器也是摧毁卫星的一种主要手段。   
At present, in addition to anti-satellite missile besides, laser weapon is destroying satellites one of the main means.  

激光武器的闪亮登场人们把光作为武器的想法,可上溯到远古时代。    
Laser weapon "shiny" on the light as a weapon of people idea, can be traced back to ancient times.   

西方在中世纪就有古希腊 <http://www.chinaiiss.com/military/view/168>科学家阿基米德用聚焦的日光点燃敌人战船的传说。 
Western in the middle ages is the ancient Greek < http://www.chinaiiss.com/military/view/168 > scientists Archimedes used a focused sun lit up the enemy warships legend.   

1960年首台激光器在美国 <http://www.chinaiiss.com/military/view/126>问世,为人们点燃了希望之光,自此人们开始了把激光器放在军事上应用这一锲而不舍的追求。
1960 first laser in the United States "http://www.chinaiiss.com/military/view/126 > come out, for the people have kindled the light of hope, since then people started to the laser on military application of this pursuit of perseverance.  

而各种科幻片中层出不穷的激光武器,已使它俨然成为未来武器的首选。
And all kinds of science fiction out of one middle laser weapon has made it has become a future weapons of choice. 

19751018日,美国在印度 <http://www.chinaiiss.com/military/view/144>洋上空的647预警卫星的红外探测器受到来自苏联西部的强红外闪光的干扰,不能正常工作。    
October 18, 1975, the United States in India "http://www.chinaiiss.com/military/view/144 > over the 647 early warning satellite infrared detector from the Soviet union by western strong infrared flash interference, can't work normally. 

19751018日,在莫斯科以南50公里处,苏联连续5次用氟化氢激光器照射了两颗飞临西伯利亚上空用以监视洲际弹道导弹发射井的美国早期预警卫星,使其红外传感器失效达4小时之久。
October 18, 1975, 50 kilometers south of in Moscow, the Soviet union 5 times in a row with the laser irradiation currently two stars in the fly over Siberia to monitor intercontinental ballistic missile silos of American early warning satellite, make its infrared sensor failure to 4 hours.  

1981年,苏联在宇宙系列卫星、飞船和礼炮号空间站上进行了8次激光武器试验均获成功。     
In 1981, the Soviet union in the "universe" series of satellite, shuttle and space station, "salute" eight times laser weapon test have been successful.    

19813月,苏联利用一颗卫星上的小型高能激光器照射一颗美国卫星,使其光学、红外电子设备完全失灵。     
In March 1981, the Soviet union using a satellite on the small high power laser irradiation a U.S. satellite, make its optical, infrared electronic equipment failure completely.     

自此,激光打太空卫星开始了,而且愈演愈烈,神秘闪光已成为太空卫星的致命武器!      
Since then, a laser space satellites started, and increasingly fierce, the "mysterious flash" has become the space satellite lethal weapon! 

3.电子干扰: 
3. Electronic jamming:  

由于现阶段我们所使用的卫星都是采用透明转发器,对地面传来的信号只是变频转发而不加以任何处理,其主要部件之一是高功放器件,一般为行波管放大器(TWTA)或固态功放(SSPA),这两种器件最主要的特点是当输入功率小于饱和点时,可以近似地认为工作在线性区,而当输入功率进一步增大超过该电平时,功率放大器就进入饱和区或过饱和区。      
Because at this stage we use satellites use transparent the repeater, ground of variable frequency signals coming forward is not to any processing, is one of the main components of high power amplifier device, generally for traveling wave tube amplifiers (TWTA) or solid power amplifier (SSPA), the two devices most main characteristic is when the input power less than its saturation point, is able to think of the job in the linear area, and when the input power over the increasing electricity at ordinary times, power amplifier into the saturated zone or supersaturated area. 

在过饱和区,不仅输出功率大大降低,而且出现大信号压缩小信号,即所谓的功率掠夺现象或功率占用,同时由于非线性的因素,还会出现大量寄生互调分量。      
In the supersaturated area, not only output power greatly reduced, and the occurrence of major signal compression small signal, the so-called "power pillage" phenomenon or "power occupied", at the same time, because of the nonlinear factors, but also can appear a large parasitic intermodulation component.     

为避免将卫星上功放推入饱和区或过饱和区,在使用中一般要实行严格的上行功率控制,或在高功放前加限幅器,尽可能使透明转发器可以避免功放工作在过饱和区。      
To avoid the satellite will push the power amplifier saturated zone or supersaturated area, in use in general to strict uplink power control, or in high power amplifier and before limiter, as far as possible, make transparent forwarder avoid power amplifier work in the supersaturated area.      

但是如果存在恶意的大功率上行干扰,转发器仍然有可能工作在非线性区,依然存在功率掠夺现象,致使正常通信业务信号或广播电视信号被压缩。 
But if there are malicious high-power uplink interference, the repeater is still possible in nonlinear work area, there is still "power pillage" phenomenon, the normal communication business signal or radio and television signal is compressed.   

对星上转发器实施干扰目前主要有堵塞式干扰和插播干扰两种形式。
The implementation of the repeater interference had blocked the main type of interference and spots interference of two forms.      

堵塞式干扰是指强占转发器的功率,将转发器全部阻塞,使通过该转发器的电视广播或通信业务全部瘫痪。
Jam type interference refers to seizing transponders power, will the repeater all jam, make through the transponders radio or TV communications services to all paralyzed.  

其干扰源的频谱可以与正常信号重叠,也可以不重叠。     
The disturbance and normal signal spectrum can overlap, also can not overlap.     

插播干扰,即利用前面提到的功率掠夺插播非法信号,使正常工作的接收台站收到干扰方的非法信号。    
Spots interference, namely using of the above mentioned the "power pillage" spot illegal signal, make the normal work of the party receiving stations received interference illegal signals.      

法轮功正是利用卫星透明转发器的弱点干扰我们的正常卫星电视广播,并采用功率掠夺的形式进行非法宣传,对此,我们除了强烈的谴责之外,更要采取积极有效措施和相应的技术手段进行反干扰。
Falun gong is using satellite transparent transponders weakness interfere with our normal satellite TV broadcasting, and by using the "power pillage" in the form of illegal propaganda, to this, we strongly condemned besides, more to take active measures and the corresponding technical means the interference.
