Of, for example can maintain the difference in temperature of 40 Celsius degrees, if the environment temperature is 30 degrees, so theoretically can get at making cold face-10 degree, actually have fever noodles to impossibly and immediately become 30 degrees.We at have fever noodles to wind up to stick another one semi-conductor system cold slice of of make cold face, by so doing it even can decline to approach-10 degree, so its make cold face and then can decline to almost-50 degree.Thus several layers add, cold carry in the making of lowest layer can attain-the super low temperature of 170 degrees.
Fold support of layer compulsorily cold component in these semi - conductors under, the noise of the receiving of new radar warning receiver unit oneself the lowest, can distinguish receives of enemy radar wave of mutually the very and small variety of .Certainly each work unit gets the power of stability exaltation also function.The signal handled a calculator to also make important improvement, it can handle 8 targets at the same time.Already the first step had the function of the electronics support measure system.
Is new domestic radar warning the receiver"eye in the sky" function Be significant to raise, at 14 inside can make sure enemy the position of soldier radar, the accuracy of the distance attains 1%.All weights just 17 kilograms.It is packed ascend Jian-10 battleplanes.Carried on a test today, each itemses all passed successfully.It clearly shows 4 Jians to the airplane pilot-8 it makes track for in 80 kilometer extroverts, there are 2 antiair radars in ground is searching it.Suddenly a ground radar reddens on the monitor, and twinkle, mean to have already targeted it.The airplane pilot immediately carried on mobile flight to get away from this threat, this to guarantee airplane pilot of safety many importance.
Developed total form antenna again afterwards, this kind of adopts to low costly print to make circuit board technique assemble.If there are among them three antennae installing, the upper part, cockpit is at the machine head front, rest 2 are located in a machine head two sides slightly lower part.This kind of combination can probe into threat radiation device of directions and height.Its signal processor is all supported by compulsorily cold parts.Pack last the electronics battleplane of our army.
The machine of our army carries radar interference the machine is under gold battery dragon's support, can say to is a power to is the strongest in the world.Can produce result while battling.Can also carry out beguilement type interference under support of"eye in the sky", after getting the detail of blast-off wave of the soldier radar of enemy, make enemy the soldier radar got a totally wrong information.
Certain place in Fukien large October 30 of radar base 19:30
This base is an important node that keeps watch on the Taiwan strait empty area radar net, will carry on the true war test of new passive radar"cool detachment II" here today.The main equipments of this base is a huge long range radar, it can probe into to 450 kilometers outside of battleplane.However it that huge antenna and blast-off of mightiness of the radar wave is the most obvious target, obviously is an enemy soldier target map ascend attractive a little bit red.It can not quickly move.Its periphery doesn't lack leave target and antiair guided missile, Gao Pao battlefield etc. protection measure.
The flank in this huge monster stopped a dynamoelectric heavy type of"strong I dragon" who has been refitted today conveyance car, the bridge house became radar operation room at the moment, the pane was covered, pilot the chair turned 180 degrees that became 3 radar hands chair.At their manipulate under rose a bulky cylinder from the cargo bay closed, the top was the very thick plank of a cake of 1.2 meters square.Had been rising till 15 meters high just come to a stop.That plank-like in shape thing changes direction the west to a side.It will soon with the huge monster of flank a definitely superiority.
We put their games for a while and introduce the concept of passive radar first.This is the end of 20th century radar the expert puts forward of a new concept:In the sky any object time all under the irradiation of peripheral electromagnetic wave, they or reflect these electromagnetic waves, or absorb electromagnetic wave, thus resulted in different from surrounding environment electromagnetic wave background of their place position.If we can probe into this so we make sure the position of these targets, need not shoot a radar wave bunch to the target in the whole process, this is the "passive" meaning.
Almost with radar at the same time in the World War II in invent of infrared locator, have already carried out in the 80's in 20th century from"active" to the "passive" conversion.We will introduce in the underneath.But the wave-length of radar wave wants greatly and gets much.American until just controled the technique " passive radar" in 2005, consigned a practical product troops to try out.Its parameter is the biggest secret.Because it not and outwardly the blast-off wave tie, the outsider peeps a path very seldom.Russia also declares that"passive radar" of Russia system threw in to undergo military service at the beginning of this year.
The radar of our army develops a technique is also walk the row is in front of the world, domestic"explored land mine to reach" really let the foreigner of those slight Chinese eat an in those early years surprised."Passive radar" item set of our army is from 1999 start climbing the bead Feng of this radar realm.Its key technique includes two, on being to have to have an extremely precise letter way to receive a machine, so as to probe into the frequency of direction empty area electromagnetic wave and flap with mutually the small variety of .Only raise enlarging of signal the magnification is nothing doing, the whole Zao voice that receive to handle a spare part to have no oneself with way before the signal.Two is a calculator system have to have already proceeded together processing ability, can handle a great deal of signal at the same time,beats by dre cheap, appear target Tu from the smallest signal difference.
Developed to have no Zao a voice the group that receive with the head letter way processor to get the superconductive expert's support.The our country has been being placed in the leading position of world and owns many famous experts at the heat superconductive research realm.However they have continuously disappeared from people's visual field and had already turned to go into each one to apply to go to in the secret research of realm since 2000 the beginning of the years.The gold Chin Hua professor is among them of a , he and his assistant Zhen great occasion of nation the Doctor took part in "passive radar" item set.After unremittingly making great effort of more than 4 yearses, they lead of the group not only provided ability at-70 Celsius degree stabilize various superconductive line of work, and develop the technique that prints to make superconductive conjunction line in printing circuit plank and chip, contribute for developing of"passive radar" making.
The calculator expert adopted an our country to develop by oneself of 64 unit vector calculator, drew up the huge but complicated signal processing procedure.Certainly the number radio frequency saves developing of system to successfully also have a very big function, it cans record down at the same time 512 signal parameters that receive unit and head letter way processor creation, is again carried on a processing by calculator.Such as front say, this saving system also developed a function in"eye in the sky".
After extremely hard effort, under the difficult condition, the first of our country mutually controls a passive radar to finally publish at the end of 2006.Just its physical volume is very huge, 512 array components and afterward the head letter of the side way the processor all need to be high strength the ground system is cold.Each direction received unit till° gets empty the electromagnetic wave of area for cent and repeatedly records it mutually and flap, together with ex- place the signal of close together unit that the processor gets to differ a value be at the same time saved a number radio frequency to save system, then through extremely high soon vector calculator processing.Get the directions, speed that should get empty to exercise inside the area object from here, at for many times scanning after can compute its distance according to its speed and sport direction.The invisible airplane will produce an electromagnetic wave in the space of"empty", passive radar's probing into "empty" ambulation equally can get directions, speed and distance of invisible airplane.
It is subjected to the power function and makes the check and supervision under cold condition, after actually measuring of the our army battleplane, reckon is apart from to 350-400 kilometers to the type battleplane of F-15, F-18 and A-10's probing into and also reaches to 280-370 kilometers to the invisible battleplane like the B-2, F-117, distance measure of the accuracy is 3%, azimuth angle of accuracy plus or minus 3 degrees.More astonishing is an American solider's"victory fairy" that it explored to measure to invade my territorial air space in 680 kilometers of distances extremely high empty invisible reconnaissance plane, targeted a target in 610 kilometers of distances.But own the reconnaissance plane of strong anti- radar ability to this but know not a thing.It drive hat with
