Description
Technical field
The invention belongs to satellite transit monitoring field, and in particular to a kind of solar radio burst interference satellite-signal event
Early warning, forecast system.
Background technology
The sun is the fixed star nearest apart from the earth, while earth light and heat is passed to, and its activity is also in all fields
Affect production, the life of the mankind, and the higher and higher technical system of mankind's interdependency.
The mankind rely primarily on radio wave to enter the communication of planet ground-air at present, and frequency range is from several MHz up to tens of GHz.
Widely used global navigation satellite system (GPS, GLONASS, Big Dipper etc.), is set by multi-satellite for ground in the world
It is standby that the service such as positioning, time service is provided, play huge effect in fields such as military affairs, scientific investigation, the probings of marine oil gas field.Navigation is defended
The transmission power of star typically only more than ten watts to tens watts or so, used frequency range, typically in L and S frequency ranges.When navigation electric wave
When reaching ground, the signal power received only about -130dBm or so, its intensity is very faint, therefore, connecing on ground
The collection of letters number is highly susceptible to an interference for surrounding environment.Exclude outside artificial premeditated interference, the master of navigation satellite signal in nature
Interference source is wanted there are two kinds, one kind is that, when gps signal passes through ionosphere, the small yardstick irregular body in ionosphere causes radio
The scattering of ripple, causes navigation signal intensity and the quick random fluctuations of phase and fluctuation, and this phenomenon is referred to as ionosphere sudden strain of a muscle
It is bright；Another is the direct interference from solar radio radiation.During solar radio solar radio burst, solar radio radiation (radio) can be big suddenly
Amplitude increase, if the frequency range of outburst covers the frequency of navigation signal, will cause different degrees of radio to disturb to GPS,
It is mainly shown as that signal to noise ratio declines.Observation shows that strong solar radio burst can interfere significantly with the reception of navigation electric wave, energy when serious
Cause receiver losing lock, even interrupt completely so that application system loses the basic functions such as navigation, positioning, time service.Therefore, wrap
It is always influence satellite navigation system performance to include the solar radio noise interference problem including GPS of America and China's dipper system
Important factor in order.
(about 100S.F.U., 1S.F.U.=10 when the radiation intensity of solar radio burst can reach quiet-22w/Hz m2)
Decades of times, or even thousands of times.By taking the outburst on March 5th, 2012 as an example, distinguish in the radiation intensity of 1.0 and 2.0GHz frequencies
Reach 501812 and 18958S.F.U.
Radio storm influences GPS flow minimum threshold to be generally acknowledged that in 4000S.F.U. or so, solar day in December, 2006
Sequence of events has been broken out in face, wherein in December day and having within 13rd L-band solar radio burst stronger twice.Fig. 3-4 be L1,
The solar radio radiation flow of two GPS communication frequencies of L2, carrier-to-noise ratio change, singly stand the gps satellite quantity that can be received and the whole world
Situations such as earth station's losing lock and position error, the change and carrier-to-noise ratio for finding two frequency radio flows are in good positive correlation.
Utilize the Traffic Anomaly and gps signal time of losing lock for having observed frequency point data statistics different frequency point solar activity
Relation, it is seen that solar radio radiation Traffic Anomaly in 1415MHz frequencies is maximum with GPS navigation signal losing lock relevance,
This has substantial connection with GPS working frequency range, as a result as shown in Figure 5.
Fig. 6 is, it is evident that this time during radio storm, the GPS stations such as Kunming, Taiwan, Wuhan, Beijing of China occur obvious
Loss of lock, and multiple stations, the complete interruption of many gps satellite signals were up to 6 minutes, during radio storm, multiple stations locks
Fixed number of satellite is less than 4 so that the real-time positioning services of GPS are entirely ineffective.
We are to Japanese wild side mountain radio telescope (Nobeyama Radio Polarimeters) in 23 week peak year
The solar radio burst that (2000-2005) is observed between greatly 6 years phases carried out rough Statistics.In 456 outbursts are observed,
Flow has 75 higher than 1000S.F.U., is higher than amounting to for 1000S.F.U. in low-frequency range (1.0,2.0 and 3.75GHz) flow
37.Observe 9 hours daily in view of NORP, such as calculated by 24 hours, it is average annual to occur to influence in peak year very big period
The quantity of GPS outburst is about 16.All it is considerable, it is seen that solar radio radiation no matter this is from the point of view of intensity and frequency
Outburst is one of inevitable influence factor of satellite navigation communication.
The content of the invention
It is main it is an object of the present invention to provide a kind of system that satellite communication is disturbed based on vacant lot translocation early warning solar radio burst
To be applied to be observed solar burst event from multiple energy sections, by the abnormity early warning of different energy section flows in microwave frequency band
The influence that solar burst is brought to satellite communication signals.
Technical know-how is analyzed：
1st, influence situation analysis of the solar radio burst signalling to each wave band wireless communication signals：
The noise that solar radio burst is introduced can be regarded as an extraneous superposition and enters receiver system in a communications system
The noise of system, if the noise is less than the noise of original system, the interference is in below system noise, and " being flooded " is in original
In system noise；To SNR influence very little.But if being more than or equal to original system noise, then original system noise will have
Risen, calculate the system noise temperature of communication system of normal temperature condition (290K) job equivalent to how many sun herein
Flow value, to determine the meeting potential impact communication system when solar radio burst flux density exceedes the value.
Assuming that the bandwidth of operation of a communication system is B Hz, its operating temperature is T (units：Kelvin) it is then extraneous to being connect
Receipts machine brings the noise power to be：
P=kTB (1)
Wherein k is Boltzmann constant：K=1.3806505 × 10-23；
Various random noise F (units：W/m2) enter antenna introduce noise power be：
Wherein G is antenna gain, unit dB；λ is observation wavelength, unit m；It is set to the equivalent solar activity stream of receiver
Amount, unit SFU, 1S.F.U=10-22W/m2/Hz；
F=B*Feq (3)
Simultaneous solution is obtained：
Then
Feq=8 π * kT/ (G λ2) (unrelated with bandwidth！) (6)
Fsfu=8 π * kT/ (G λ2)*1022 (7)
Or Fsfu=8 π * kT*f2/(G*c2)*1022 (8)
The conversion of reception system external noise flux density is obtained from formula (7) and formula (8) close for equivalent solar radio radiation flow
Spend to be inversely proportional with antenna gain G, and square being inversely proportional for operation wavelength λ, or square be directly proportional to working frequency f, this
Mean that：
1st, higher in antenna gain G, its system noise flux density is converted as equivalent solar radio radiation flux density level just
Lower, smaller solar radio burst, more easily causes the rising of external noise, such as common portable equipment (miniature antenna)
By being influenceed to be less than large-scale ground station equipment (big antenna)；
If the 2, the antenna working needle of same gain G is to different frequencies, more low-frequency communication system, external noise stream
Metric density conversion be solar radio radiation equivalent flow density it is lower, be this in solar radio burst, lower radio flow
It is easier to cause the increase of outside noise, so the communication of low-frequency range is easier to be affected；
3rd, to the same antenna, due to the difference of its radiation pattern, possible antenna points to the anaplasia with sun angle
It is also different by being influenceed during change；
Fig. 7 is to be converted into equivalent solar radio radiation from different communication mode noise power spectral density in 10MHz~20GHz bandwidth
Flow power spectral density value (sets the antenna for working in G=10dB)；
To sum up, we have counted the receiver noise of several typical communication modes (below 10GHz) and its antenna form
Equivalent sun flow：
1st, short wave communication (Short-wave Communication)：Frequency range 3MHz~30MHz, be through ionosphere
Reflection gets to receiving device, and the solar radio radiation signal of the communications band is typically all ionized layer stop, it is impossible to reach the earth
Surface, is the influence very little that this is hardly signaled by solar radio burst；
2nd, microwave communication (Microwave Communication)：Frequency of use is entered for 300MHz~3THz electromagnetic wave
Capable communication, including terrestrial microwave relay communication, tropospheric scatter communication, satellite communication, space communication and work in microwave ripple
The mobile communication of section；
Wherein, the most communication handset general work of our routine uses in GSM frequency ranges (900-950MHz and
1800MHz), CDMA frequency ranges (820-900MHz), general antenna for mobile phone uses microstrip antenna pattern, and antenna gain G is 3-8dB left
The right side, with the maximum wave beam alignment sun of G by formula (8), outside noise conversion is equivalent sun flow in 1100SFU-1300SFU
(<1GHz) with 3400SFU (1.8GHz) left and right, while mobile communication base station typically uses electromagnetic horn, gain G is in 12-18dBi
Between, with the maximum wave beam alignment sun of G by formula (8), outside noise conversion is minimum left in 600SFU for equivalent sun flow
The right side, but we are general when using mobile phone, mobile phone and the general misalignment sun of the maximum wave beam of antenna for base station, solar radio burst
Signaling, to enter the power of receiver by antenna be very little in fact, be this mobile communication signal by solar radio burst this
Plant influence possibility very little；
More wifi is used in our daily lifes in addition, bluetooth (Bluetooth) works in 2.4-2.485GHz, its
The short-range data being primarily directed between fixing equipment, mobile device and building LAN is exchanged, and is typically penetrated by the sun
The possibility very little of electric radiation, and transmission range is short, transmission power is strong compared to solar radio radiation flow, also typically will not be by too
The influence of positive burst；
For deep space communication, its target is the equipment such as satellite, aerospace craft, the space station in space, and its communication mode is determined
Its fixed solar radio radiation signal may enter its system by its antenna, and its frequency of use mainly divides as follows：
Table 1 is used for the radio division table that deep space is studied
By the analysis of formula (8), the conversion of reception system external noise is that equivalent sun flow is into anti-with antenna gain G
Square it is directly proportional than, and square being inversely proportional for operation wavelength λ, or to working frequency f.Communicate and believe for 5GHz-10GHz
Number, receiver noise conversion is above more than 19000SFU to equivalent sun flow, and the signal of more than 10GHz communication frequencys connects
The conversion of receipts machine noise is above more than 50000SFU to equivalent sun flow, according to the system of Nobeyama solar radio astronomy platforms
Meter：Solar radio burst flow exceedes in the several monitoring frequency ranges (9.4GHz, 17GHz, 35GHz) of more than 5GHz over nearly 10 years
25000SFU event is no, illustrates that solar radio burst exceedes the probability very little of threshold event in more than the 5GHz, too
Positive burst event influences also little to more than 5GHz deep space communications.But for S-band (2-3GHz) signal of communication, have
Certain influence.
For operating mainly in L-S frequency range navigation communication systems, be also it is air-ground between communication, some main navigation systems
The working frequency of system such as following table：
The working frequency of each navigation system different frequency range of table 2
Through statistics, 1SFU solar radio burst is exceeded in the solar activity peak year probably at average annual 49.31 times or so, and
The solar radio burst for exceeding 1SFU the sun quiet years is probably as shown in Figure 8 at average annual 7.03 times or so：
Since 24th solar cycle (2010 start), multiple solar radio radiation is broken out respectively in 1GHz 2GHz 3.75GHz by force
The traffic conditions (data source Japan wild side mountain solar radio astronomy platform) of 9.4GHz17GHz each point frequencies
Strong radio burst statistical form since the solar cycle of table 3 the 24th (2010 start)
To sum up, it has been found that X-band is hardly affected during solar radio burst, and in L-S wave bands
Navigational communications signal be most susceptible to solar radio burst event influence.
For this, our selected X-bands (8-9GHz) monitor the signal launch load service band of satellite as space.
2nd, in terms of x-ray observation can early warning theory analysis
X-ray is the important wave band of sun observation, is largely had when solar flare breaks out, we have counted the 24th too
In positive active cycle, the relation that X-ray flow rises between the rising of radio flow during flare burst is as follows：
According to the difference between X-ray energy spectrum index during solar burst (spectral index) δ x and radio power spectrum δ r
Different, although both meet power law spectrum signature, radio spectra becomes to more they tend to gentle in onset process, is this in multifrequency
In section (radio and high energy) outburst discharge process, X-ray rises compared to radio flow soon, peak value is reached earlier, such as Fig. 9 institutes
Show：
Simultaneously according to Adriana V.R.Silva et al. by the observation to the multiple solar flare outburst moment, summarize X and penetrate
Differences of the line power spectrum δ x and radio power spectrum δ r between two kinds of outbursts of impulsive and Non-impulsive, δ x are all higher than δ r such as
Shown in following table：
Relation table in the outburst of the solar flare of table 4 between HXR X-Ray and the different spectrum indexs of microwave frequency band
| Spectral index | All | impulsive | Non-impulsive |
| δx | 5.8±0.8 | 5.9±0.9 | 5.7±0.6 |
| δr | 4.8±1.0 | 5.1±0.9 | 3.7±0.6 |
| δx-δr | 1.0±1.0 | 0.8±1.0 | 2.0±0.7 |
In addition the time difference between Microwave Bursts peak value-X-ray outburst peak value is also demonstrate that from observation angle.According to
Repeatedly typical solar flare breaks out X-ray peak flow to 17GHz to the 23rd solar cycle by T.Kawate, N.Nishizuka
Time difference between radio peak flow, find and the research of above-mentioned spectrum index meet, i.e., radio peak flow and X-ray peak value it
Between existence time it is delayed；Simultaneously we by L the monitoring frequency time to peaks of S-band two compared with the X-ray time started,
It has also been found that time lag is between 3-30 minutes, it is as shown in the table：
The relation of X-ray activity time and radio correlative flow time in the 23rd solar cycle multiple typical motion of table 5
Exceeding so since flare burst to radio flow disturbs the threshold value communicated just there is also the time difference, and we count
During the multiple solar activity of the 24th solar cycle X-ray begin to ramp up i.e. solar flare start the outburst moment to burst it is extremely strong when
There is following distribution time difference between quarter：
X-ray was begun to ramp up between the burst extremely strong moment during the multiple solar activity of the solar cycle of table 6. the 24th
Time difference
By above-mentioned analysis and statistics, there is the flow of X radio different before violent solar radio burst reaches extremely strong value
