Embodiment
With reference to specific embodiment and accompanying drawing, the present invention is further described.
A kind of simulation test for the method for realizing shortwave multi-channel parallel and simultaneously and rapidly capturing and analyze disclosed in embodiment
System, its equipment being applied to mainly have：Multichannel receiver (abbreviation receiver) one, function waveform generator are (i.e. any
Function generator) one, PC either movable termination (operation windows operating systems) one, indoor test antenna or
Load two, in addition to the multichannel receiver test software in PC or movable termination, connected mode such as Fig. 1 institutes
Show.
Traditional signal source can only send the signal of single, in order to simulate multi channel signals source, be used in embodiment
Function waveform generator KEYSIGHT M9505A are as signal source generating means, based on MATLAB softwares by shortwave frequency range
9467 signals synthesize a bars (i.e. composite signal) and send (i.e. one composite signal of each transmission, every synthesis letter afterwards
Number include 9467 signals by frequency point), and design the signal time delay of different frequent points signal (i.e. each signal).Specifically
, MATLAB designs can be used by the synthesis of 9467 signals, equivalent to leading to after signal is synthesized into a bars on waveform
The sending port for crossing arbitrary-function generator is sent, and is sent composite signal using load or indoor test antenna, then pass through
Load or indoor test antenna receive composite signal to the receiving port of receiver, by the signal received by receives frequency point
It is fitted in 9467 signalling channels (abbreviation passage) that receiver has, the frequency of reception signal is corresponding to this 9467 passages
Set in advance, i.e., each channel number (numbering of signalling channel) binds a frequency, and each signalling channel is corresponding one
Fixed signal, and signal time delay by setting in advance when design sends waveform in signal source generating means on a different frequency
It is fixed.For example, freq=1.6MHz+n*3KHz, n are exactly channel number, freq is exactly frequency.
It is as follows that rule is devised in the time of signal source generating means transmission signal：
Using the algorithm of mould 10 (Mod10), that is, be equal to divided by 10 remainder, such as 1mod10=1,11mod10=1,
12mod10=2 ....The fiducial time stamp sent is used as by the use of passage of the channel number mould 10 equal to 0, it is assumed that channel number mould 10 etc.
In 0 passage send the time be T, shift time be Δ t, then channel number mould 10 be equal to 0 passage transmission the time be exactly benchmark
Time, delay time 0；Passage transmission time of the channel number mould 10 equal to 1 is exactly 1 Δ t of delay on fiducial time, also
It is T+ Δs t；Similarly, passage transmission time of the channel number mould 10 equal to 9 is be delayed fiducial time 9 Δ t, that is, T+9 Δs t.
For example, the signal of 0 passage (1.600MHz) is in fiducial time T0On send, then the letter of 1 passage (1.603MHz)
Number just in T1=T0+ Δ this time point of t sends, and the signal of 2 passages (1.606MHz) is in T2=T0+ 2 this time point of Δ t were sent out
Go out, 10 passages (1.630MHz) are again in T0Sent on this time point, 11 passages (1.633MHz) are again in T1This when
Between point on send, and so on.That is, function waveform generator in analog signal generating process, is calculated according to mould 10
Method, 0 passage of receiver, 10 passages, 20 passages ..., 100 passages ..., 1000 passages ... wait passage of all moulds 10 equal to 0 to connect
The transmission time point of the signal received is fiducial time T0, by that analogy, the signal of 9467 channel receptions on receiver
Transmission time point shares 10, i.e. T0~T9.By this method, in order to instructing test software quickly to identify multi channel signals
Validity.
According to above-mentioned explanation, the time can will be sent with formula Tn=T0+ n Δs t summarize, n=0,1,2 ... 9.It is worth saying
Bright, shift time Δ t is set in advance according to the performance characteristic for sending signal source and multichannel receiver etc., it is desirable to must
Must be the multichannel receiver sampling time integral multiple or 0 times, designed shift time Δ t, the signal on different frequency
Delay is also determined that, corresponding, and relative time (time i.e. relative with fiducial time) is received corresponding to different channel numbers
Just it can determine that.For example, multichannel receiver sample rate is 4.8K, a sampling time is (1/4800) second.Said according to above-mentioned
It is bright, shift time formula Δ t=N* (1/4800) can be summarized, N is the integer more than or equal to 0.Discrete digital signal processing
In the concept of sample rate generally be present, sample rate 4.8K is exactly briefly that receiver goes to sample and believed per (1/4800) second
Number, just recorded if there is useful signal, that is, time interval is (1/4800) second between every double sampling.
Buffering area of the design of multichannel receiver inherently containing storage signal, once receiving signal, multichannel receives
Chance, which stamps information, receives timestamp and by signal characteristic (for example, signal noise value, signal strength values, frequency deviation, channel number
Deng) temporarily storage is to buffering area in the form of data, so that PC is read；It will be sent out using the multichannel receiver test software on PC
All signals in the time are sent all to be read out in a manner of network data transmission udp protocol；Then test software meeting
Analysis process is completed according to following steps, analysis process mainly realizes synchronizing signal and the statistics of empty signal.
It should be noted that in practice, the transmission time of signal is indefinite, it is possible to simultaneously, it is also possible to
There is a deviation, in order to improve the accuracy of the receiving ability of test multichannel in embodiment, we will do the time in design
Rule is stated, real signal is simulated as far as possible and sends scene, but this rule can't influence the quality of signal.Therefore, the survey
Method for testing also can objectively react the multichannel receptivity of receiver very much.
With reference to shown in Fig. 2, concrete analysis process is as follows：
1) fiducial time is found out：Signal (0,10,20 ..., 100 ..., 1000 ...) of all moulds 10 equal to 0 is extracted
Come, received with most of these signals from the point of view of the method for statistics on which timestamp, that timestamp is it can be assumed that be me
Fiducial time T0。
For example, signal source generating means have sent a bars (i.e. composite signal) for 9467 signal synthesis, multichannel
Receiver have received 9000 signals in the t1 times, and the t2 times have received 267 signals, and the t3 times have received 200 signals, that
Fiducial time is exactly T0=t1, then the signal can that t2, the t3 time receive is proved to be empty signal.
2) according to obtained T0With known Δ t, transmission time of the non-zero each passage of other results of mould 10 is calculated,
Calculate T1,T2,T3…T9：T1=T0+Δt,T2=T0+ 2 Δ t ... ..., T9=T0+9Δt。
Multichannel receiver test software sectional drawing as shown in Fig. 3~Fig. 5, the Δ t=N* (1/ in the test environment
4800), N 16.Arrive here it is known that, which passage should correspond to T0~T9Which timestamp, that is, the signal received should
It is somebody's turn to do and is sent by which transmission time point.Note, reception time (stamp) here and transmission time (stamp) though there is certain time-delay, phase
It is identical to the time and very short, and the present invention is more concerned with relative time, therefore, to simplify the analysis, will in the present invention
Two times are equivalent to a time, it is believed that it is a meaning to receive time and transmission time.
3) signal and incongruent signal complied fully with timestamp and channel number is counted.
Wherein, the signal that particular channel should occur on special time stamp is summarized as complying fully with signal, otherwise concludes
For incongruent signal.For example, in T3Timestamp on the channel number that should occur should all be 3 passages such as the result of mould 10.And
The signal signature that will fit completely into is synchronizing signal, is empty signal by incongruent signal signature.
4) synchronizing signal under each timestamp and empty signal are collected.
Statistical result as shown in figure 3, have recorded the sum of the signal of each speed sequence number received, reference synchronization head,
The information such as temporal information, sync rates, speed therein are equivalent to adjust during we live equivalent to a kind of specific transmitted waveform
Frequently, amplitude modulation etc., the speed of the signal sent every time can be adjusted.
As shown in figure 4, by taking the waveform of Fig. 3 medium-rates sequence number 4 as an example, signal source agreement sends one by 4733 signals every time
Composite signal is synthesized, we have received 475 signals altogether on passage of the mould 10 equal to 0, wherein 473 in a time
On, others 2 are on the time unknown in addition, according to T1=T0+Δt,T2=T0+2Δt……T9=T0+9Δt.Ask one by one
It is logical that the signal received on the passage of the grade of depanning 10 1, the signal ... ... that mould 10 receives on the passage equal to 2, and mould 10 are equal to 9
Signal on road, receives altogether correct signal (i.e. synchronizing signal) totally 4727, and error signal (is also garbage signal or empty letter
Number) totally 15, it is 4727/4733=99.87% so as to obtain the reception sync rates of the receiver.And what is had more is exactly empty letter
Number, as the generation of empty signal, it may be possible to it is various the reason for caused by, for example disturb, intermediate frequency, image frequency produces, and this is not belonging to
The field of our this invention research, belong to post-processing, and how remaining 15 error signals (corresponding false synchronization head) are
The needs of output are studied in addition, for example, because the reasons such as interference, intermediate frequency, image frequency produce, but this not the invention solves technology
Problem, no longer illustrate here.
5) to single passage query analysis.
Such as Fig. 4 and Fig. 5, synchronizing signal and empty signal message are inquired about respectively, what the time list in Fig. 4 and Fig. 5 showed is exactly
The timestamp of the signal, channel row are exactly the channel number of the signal, and powPeak row are the intensity of the signal, and powNois row are these
The noise of signal, frequency deviation row represent the frequency deviation of the signal.Later stage can pass through recorded signal characteristic, i.e. multichannel short-wave reception
The receptivity of equipment evaluates relevant parameter information, including the information such as signal noise value, signal strength values, frequency deviation, channel number
To analyze the reason for producing empty signal.It should be noted that the reason for empty signal will according to the software provide signal intensity, letter
Number noise meter calculates signal to noise ratio, judges Producing reason in conjunction with combined factors such as frequency deviations, specifically how to calculate and is not belonging to this specially
The scope that profit discusses, therefore do not repeat herein.
In practical application, the acceptance of corresponding shortwave multichannel receiver can be measured exactly by the above method
Can, solve the confinement problems that can not be tested simultaneously the multichannel of multichannel receiving device in the prior art, realize parallel, same
Step, quickly multichannel test simultaneously, obtain correct signal (synchronizing signal) number, error signal that each passage receives
