[accipitral eye plan says martial editor's note] the development through nearly 15 years, china established a global monitoring network that forms by reconnaissance satellite of more than 20 for military use, current, the dimensions of this system and actual strength already were next to the United States, and China has stepped the 2nd group such as Europe Russia day in domain of reconnaissance satellite technology, and its develop still accelerating, this is the little-known progress in modernization of Chinese military affairs. This period the plan announces for you the satellite of for military use with giant liberation army develops a plan, discuss its far-reaching influence.
China has launched satellite of series of many remote sensing in recent years, blast off so frequent, but Chinese government is very brief however to its report, mention this satellite to basically be used at estimate the yield of census of natural resources of scientific test, land, crop and take precautions against natural calamities to decrease the domain such as calamity only commonly. The fact is not confined to this for certain, the media of western military affairs such as brief family name thinks remote sensing series actually of reconnaissance satellite of Chinese for military use external title, be similar to Russia to name satellite of for military use in those days for the universe (Kosmos) series.
Because close ground space is being monitored by rigor,this is, to prevent the miscarriage of justice between the nuclear power, any countries launch a satellite to want to be announced to the outside. China, before Russia notes an effect quite, give reconnaissance satellite of for military use the coronal with one does not have name of colorific of for military use. The history of satellite of remote sensing series is very short, remote sensing satellite just blasted off 1 number on April 27, 2006 enter the space, but its development is very rapid however, already did not launch 33 satellites to 8 years.
Arrive besides several among them outside birthday invalidation, still large quantities of satellites work normally in aerospace, formed the network of surveillance of whole outer space that includes radar and optical scout faculty, this also is besides the scale is the largest day besides satellite of American NROL series base spy network. On some kind of meaning for, the occurrence of satellite of remote sensing series, it is our country the army and the people use into the mark that begins depart like the satellite.

On some kind of meaning for, the occurrence of satellite of remote sensing series, it is our country the army and the people use into the mark that begins depart like the satellite.
The picture is satellite of high component series. In addition, reconnaissance satellite of for military use still got the complement of civil satellite, the satellite of high component series that develops in recent years for example. It is reported, high component is special it is finger height resolution system of right observation satellite constellation, it is the State Council release " long-term science and technology develop program outline in the country (2006-2020 year) " in 16 affirmatory great and special one of.
To the bitter fleabane of satellite of series of our country remote sensing suddenly develops, foreign military affairs observes lover of the home, spaceflight also is interested very much, they differentiated for satellite of remote sensing series according to all sorts of reports and data type. According to the article of Gunter's Space Page of famous spaceflight website, main component is satellite of remote sensing series 3 kinds, reach for thunder like reconnaissance satellite, 2 become for optics like reconnaissance satellite, these two kinds all are transmitted for data model satellite, the photograph that films namely passes a ground through radio data catenary directly, do not need to return film.
Chinese radar is become become like reconnaissance satellite and optics can differentiate again like reconnaissance satellite amount to is acting. Say radar is become first like reconnaissance satellite, radar is become resembling is to show the star carries synthetic aperture radar to synthesize ground photograph through accumulating signal, synthetic aperture radar becomes the resolution that resemble more optical into like difference, but it is had not the harsh weather such as dread rain snow, can penetrate the advantage of the pall such as upper tree, brushwood.
A satellite is remote sensing namely synthetic aperture radar is become like the satellite, thunder of aperture of generation synthesis reachs our country to still include remote sensing like the satellite date and 3 remote sensing 10. According to foreign report, remote sensing 1, use L wave band 3 numbers to synthesize bore diameter radar with 10, highest resolution 5 meters, backward world advanced level is more, but the breakthrough that serves as a domain, remote sensing still had the honor to win award of special grade of progress of national defence science and technology 1 number 2007.
6 date, remote sensing mix remote sensing 13 numbers remote sensing is considered as the 2nd generation of our country 18 numbers to synthesize bore diameter radar to become like the satellite, go up relatively the improvement of generation was to use X wave band to synthesize bore diameter radar. The wavelengh of X wave band is smaller than L wave band much, into also promote greatly like resolution, according to guessing remote sensing 6 highest resolution may achieve 1 meter.
This index already perfectly, remote sensing blasted off 6 numbers on April 22, 2009, radar becomes the synthetic aperture of contemporaneity Japan to also be 1 meter like satellitic resolution. Be being returned with American difference of course is very big, the United States is in early the 20 many lacrosse year ago synthesized bore diameter radar to come true with respect to use X wave band on the satellite highest 0.3 meters resolution, of the working mode of lacrosse satellite, what scanning handles ability is strong also be remote sensing 6 look at its a person's back hard.
The picture is remote sensing before 17 satellites blast off. Optics is become like the respect, satellite of remote sensing series developed 3 generation, remote sensing 2, date and 11 4 date, 7 satellites are generation, remote sensing 5, it is the 2nd generation 12 numbers with 21, 14 satellites are remote sensing the 3rd generation. Remote sensing 2 satellites blasted off on May 25, 2007, it is resolution becomes our country highestly at that time resemble reconnaissance satellite, highest resolution is 2 meters. This index lags behind at international far advanced level, the country such as the United States, France and Russia does not say for the moment, came true with respect to India at that time inferior of rice class into like resolution.
Although development of reconnaissance satellite of Chinese for military use obtained tremendous progress, but compare with American photograph very backward still, the resolution of satellite of civil remote sensing of the United States in the graph is 0.31 meters, and at present satellite of the most advanced remote sensing of for military use also reachs our country only 0.45 meters of class, civil satellite of the United States is more advanced than the satellite of for military use of our country, difference sees one spot, china still will continue hard henceforth, catch up with the United States.
