Abstract

The invention relates to an anti-stealth background radar and a use method. The method comprises the following steps of: enabling a radar to continuously emit narrow-beam electric waves which are reflected into echoes by the ground; enabling the radar to receive the echoes because a shot-down stealth aircraft can break out the echoes, the same to plasma, and other aircrafts can be detected because of different strengths of reflected waves or different travel values, even for a device emitting interference radio waves. The invention can be used as a common air defense radar or arranged in an aircraft or missile to chase enemies, especially can be made into an phased array, is cheaper and easier to manufacture and use than a traditional radar with the same efficacy by being arranged in an early warning plane or other places, rapidly and easily disarms a stealth incursion technology with advanced confidentiality and great investment, is easy for nations indignant at the stealth technologies of America and Russia to collect national geomorphology materials to extrapolate and compare echo conditions by then, exposes invaded high-tech aircrafts because of distinctiveness and is also easy to lay extremely-cheap aluminum foils to aid the reflection of echoes so that electric waves of broadcasting, televisions or mobile phones can also aid the radar by referencing the method.

Description

Anti-stealth background radar and usage

Affiliated technical field:

The present invention is a kind of radar system that is mainly used to detect concealed aircraft, and attached usage.

Background technology:

Existing known, 21 century from the beginning of, US military is boasted the raid effect of its concealed aircraft without restraint: " a F-22 aircraft is promptly defeated ten Sino-Russian advanced fighter planes.".Attract many Da Hua people's of government money earned by hard toil will buy stealth aircraft, again emerging nation's demonstration has been caused very big new inequitable deterrence.Does tangible unfavorable peaceful development also against openly, disclose fair science and democracy spirit?

Summary of the invention:

Take precautions against the raid of concealed aircraft for honest and clean changing places, safeguard peace, the invention provides a kind of anti-stealth background radar and usage.And remind superstitious stealthy patient, and meaningless spending done this trifling matter of deceiving oneself, and the Guangzhou citizen also easily find out much the indigenous method that cracks " stealth "! Continuous back also has " intersection point radar ", " magnetic radar ", " radio radar ", " sunflower-type is faced upward and sought hot radar ", " satellite infrared radar ", " parallel lines electric capacity radar " ...Still the popular government that could allow is strong!

The present invention solves the technical measures that its technical matters adopts:

1, the topography and geomorphology that can accurately detect the front lower place with reference to cruise missile realizes recognizing the example of road intelligence flight, can be contained in the landform detection radar on the big-and-middle-sized air defence missile, allow the vertical directive eminence of guided missile, when under back, flying again, do not stop moving landform detection radar, surveying the topography and geomorphology that in advance does ripe already,, all can make this survey not normal and be tracked to if when having aircraft therefrom to block.If aircraft is stealthy, then must absorb the electric wave of radar, performance is especially unusual, need not to spend the differentiation time in addition again, promptly traceablely is.Like this, concealed aircraft is easier being tracked to just, it can't discharge again again at all any can be as itself the scapegoat of big absorption electric wave; Disturb electric wave if this aircraft sends,, all must fix a point to disturb electric wave that landform knows more significantly and by " fixed point " tracking then because of any aerial electric wave emissive source all can only be a point-like.And all stealths or putting the aircraft that disturbs electric wave, its motor-driven fistfight performance and to evade performance all very poor is unable to escape in fact and has been taken off.Rescue it if other aircraft will go out to disturb, then will want to hide at a distance, then definitely can't disturb above-mentioned landform to reach with surveying nearby to being unable even to protect or fend for oneself.

2, allow geostationary satellite or rise balloon, or dirigible etc. is taken the landform detection radar and is hovered in the high-altitude or atmospherical stratosphere place goes out radar wave repeatedly and strafes ground everywhere in fixed point ground as far as possible, real-time collecting is tried one's best ripple data that the real terrain morphologic characteristics forms with record, one finds that this ripple has different, should promptly follow the tracks of, enemy's situation is arranged, should promptly guide above-mentioned guided missile or other weapons to attack it.Thereby the enemy who had both paid attention to preventing stealth or put interference does not let slip having opposed of routine too.Also can be extended to present technique on the prior-warning plane.

The invention has the beneficial effects as follows:

1, efficient: as at first easily to catch stealth [even the plasma stealth too] and put enemy's aircraft of interference, can say so substantially and not let slip.

2; Lian Yi: be connected in slight; that will fly to supervise in the utmost point bad working environment in the other side sky and also can detect the enough topography and geomorphologies at a distance in front lower place effectively by the utmost point in the not very too valuable cruise missile; then main air defence missile in the spatial domain work that oneself is familiar with; also have that to rise balloon; satellite or other delivery vehicle carry very reposefully to be established and the surveillance radar element of putting the space to good use is arranged greatly; just easier: as allly when can not receive normal echo, noted very easily reaching the object of the invention, and this working method must to be watched out for and bumped against the easy of front landform and implement manyly at any time than cruise missile.In addition, the landform detection radar is in fields among the people such as aviations and have and much use, and has and can use for reference the convenience of using.Even can be compatible mutually.So the present invention can know the easier enforcement of air defense radar than now and popularize.

Description of drawings:

The present invention is further described below in conjunction with drawings and Examples: its only Fig. 1 is performance the present invention proposes when rising balloon and carry the landform detection radar and find concealed aircraft in the high-altitude as delivery vehicle the stealthy background radar and the synoptic diagram of usage.

Among the figure: 1, delivery vehicle; 2, radar I antiposition; 3, electric wave bundle; 4, echo; 5, aircraft; 6, ground; 7, radar ∏ position.

Embodiment:

As shown: delivery vehicle 1 can or rise balloon by various aircraft or spacecraft and serve as---and the initial stage is that economical easy again enforcement and master benefit the native country air defense, can lack mobile dirigible or balloon again relative to the earth to the high-altitude of trying one's best by hovering and serve as.[initial stage can be adopted the old-fashioned landform detection radar of being strafed than the narrow beam electrically oriented wave by mechanical rotation common and that range is far away of trying one's best to the radar that it is taken, extend to other later on again]---when it is in radar I position 2 and other and can be directed to the directive on ground 6, can allow this radar system receive the therefore echo 4 of reflection of ground 6---preferably can so operate with each hover point repeated multiple times under at various meteorological conditions in non-belligerent period to send electric wave bundle 3.As often as possible collect accumulation electric wave bundle 3 strafe can and scope in the true echo 4 of topography and geomorphology when nothing is subjected to other artificial interference more as far as possible various data in addition add the sense organ of remembering operation monitoring; Supersign is the stroke [being again the stroke of electric wave bundle 3 in fact] and the strong and weak value of echo 4.Conversion is cut to be located on various relevant aircrafts or guided missile or other delivery vehicle for this radar system [or even another type] and is arrived in by plane " the reckoning value " of corresponding each place under corresponding condition again.By the time during their belligerent warnings, all penetrated corresponding electric wave bundle 3 the data [even impression] of reflection wave when different [for example stroke or strong and weak value difference are different surpasses 10%] being arranged with " reckoning value ", promptly vigilant is that electric wave bundle 3 is interfered with by external aircraft 5, note having defended oneself.In case the disappear of echo in operate as normal, promptly need not to contrast " reckoning value " again even if all should suspect this electric wave bundle 3 under any foreign environment is absorbed by the aircraft 5 of stealth or disturb mistake, the direction that promptly is equivalent to electric wave bundle 3 is the state that goes to shown in the radar ∏ position 7 among the figure.So far, just very easily by skilled manipulator or even mechanical automation ground when these electric wave bundle 3 these shapes of all chances, promptly only allow it turn over again but orientation and the sensing of the little angle of trying one's best [inertia is inevitable] when back as far as possible being controlled at this shape of firm chance very fast again strafed fast back and forth nearby greater than zero; If the aircraft of really strafing 5 is stealthy words, must see more than 4 frequent strange elephant that disappears of echo---only inquire for these 4 to 5 times and only about 3 seconds consuming time, just very easy examining known its aircraft of strafing stealth 5, also very easy like this just can this aircraft of track lock [join in addition more sophisticated equipment is just better].So reaction velocity is known radar more than fast ten times than now, and has simplified electronic equipment greatly.This method also should tackle other aircraft, especially in the timely segment limit in spatial domain that known our control does not fly into, all strokes of herewith frequently seeing echo 4 and strong and weak than just revealing amplitude nearby greater than 10% flash when changing, just strafed disagreeableness aircraft substantially as can be known, even can save the trouble that will chase after the track of taking off this aircraft and speed and consuming time, action subtracts the danger that is subjected to its evil greatly early.If the above-mentioned phased-array radar etc. of being matched with is also very easily accomplished with regard to better effects if.For example: easily establish this radar and be penetrate many bundle electric waves and as the thorn of hedgehog pointing space all directions and try one's best rationally uniform, as long as just doing the space of smaller angle, this integral body changes pendulum, just easily make the scope of strafing of each electric wave bundle 3 connect nearly, do not have the ground of leakage and covered a certain spatial domain.Less because of this angle of changeing pendulum, it changes the pendulum cycle must be less, thereby can significantly reduce the crisis that each point is owed to strafe in this spatial domain.And its each adjacent electric wave bundle 3 also easily respectively adopts the electric wave of different frequency to distinguish; Be attached to the characteristics that the present invention's reaction is exceedingly fast again, order enemy aircraft extremely difficulty has escaped.Be to ensure effect, be preferably in to make in the normal range of operation to the width of electric wave bundle 3 or diameter and be not more than that 2 meters dawn are distributed diffusion less and as far as possible [early the having precedent] of concentration of energy on a straight line.Its working range limit is all need in the paragraph of warning on the five meters wide banded ground all have be mapped to the key element that but can not receive echo [for example: significantly mulch film, tent, inflatable building or waters etc.---this examination during easily in start] top by this electric wave and should be provided with metal forming, sheet or iron net [waste and old is good], can both be reflected into echo 4 to electric wave bundle 3 everywhere with what guarantee this scope.This is hundred meters [probably stormy waves invasion and attack in the seashore limit, this place is rare significantly mulch film, tent, inflatable building or reservoir, lake] and the place of military importance other be easily to reach, and spend usually also less [as long as scattering not a lot of aluminium foils, entanglement etc.], even if the new aluminium foil whole nation of establishing 40,000,000 meters long, five meters wide China mainland, even if also only need about 500,000,000 dollars---so far the wave launcher of mobile phone or pager even remote-control toy has all easily repacked anti-stealth background radar into reference to the present invention.
