Vehicle data is provided according to acquisition module；
Short distance anti-collision system detects surrounding vehicles, is mounted on test ride vehicle；
The short distance anti-collision system, including radar, centre frequency f are 24.125GHz, and transmitted waveform is sawtooth wave and constant frequency
The first segment of the combined waveform of wave, the waveform is sawtooth wave, and period 10ms, working frequency variation range is from 24.025GHz
Change to 24.225GHz, bandwidth 200MHz.Second segment selects constant frequency wave, period 10ms, working frequency 24.125GHz.
Transmitted waveform is as shown in Figure 2.
Short distance anti-collision system processing method includes the following steps：
S1. the collected I/Q datas of A/D are gone by direct current after partial data point before removing, carries out time-frequency by each section of waveform
Time domain data is converted into frequency data by FFT transform；
As a kind of technical solution：The method of the FFT transform of the time-frequency of step S1 is：To the first segment sawtooth in channel 1
Wave FMCW, the collected I/Q data of second segment constant frequency wave CW, A/D carry out the FFT transform of 512 points of time-frequency, in channel 2 respectively
The collected I/Q data of second segment constant frequency wave CW, A/D, carry out 512 points of time-frequency FFT transform.
Partial data point before the removal is exactly first to get rid of the collected preceding parts AD in the collected data of AD
Data point, for example, if collecting 700 points, gets rid of preceding 50 points, the data from 51 to 700 generally in 50~70 points
It removes direct current and carries out FFT transform.Why getting rid of this partial dot, there are two reasons, when inside these data, part number
According to being since waveform is when transformation, the pulse that voltage generates causes this partial data abnormal, second the reason is that due to away from
The reason of from fuzziness.This part is said before the reason of causing distance resolution to reduce, and is the line of transmitted waveform in fact
Property degree, cause this resolution ratio reduction.
The method for removing direct current in step S1 is：
(1) mean value of the I before the removal of calculating 1 sawtooth wave band of channel and constant frequency wave band after partial dot, Q data calculates logical
The mean value of I, Q data before the removal of the sawtooth wave band in road 2 after partial dot；
(2) for each above-mentioned I, Q data, the mean value of respective I, Q data that previous step is calculated are cut, then it is complete
At the mode for removing direct current；
(3) I/Q data goes the direct current calculation formula to be：Wherein, I indicates I ways
According to I ' is to go the data after direct current, and Q indicates Q circuit-switched datas, and Q ' is to go the data after direct current, after N indicates the preceding partial data point of removal
Remaining data is counted；
The I after direct current, Q data are removed, the data mode of I+jQ is merged into, then carries out windowing process, it will be in channel 1
First segment sawtooth wave FMCW, second segment constant frequency wave CW, first segment sawtooth wave FMCW in channel 2, respective data carry out windowing process.
Hanning window or hamming window etc. can be selected, secondary lobe is reduced, to improve the detection performance of target；Hanning window can cause main lobe to add
Width simultaneously reduces, but secondary lobe can be substantially reduced.
Hanning window calculation formula is：
S2. the plural modulus value after FFT transform of each section of waveform is done into CFAR Threshold detections, after CFAR Threshold detections
Data, it is a range cell to enable each data, and carrying out binary system to the data of each range cell adds up, and exports
First peak point of thresholding, is calculated phase；
As a kind of technical solution, the method that the binary system of step S2 is accumulative is：
If the data of the range cell cross thresholding, it is denoted as 1, if not having thresholding, is denoted as 0, is then carried out more
Period accumulates, if the number of the thresholding of some range cell accumulative 1 is more than K, the number of the declaration of will accumulative 1 of K, and mistake
The point of thresholding is denoted as 1, when accumulative 1 number reaches K, then exports the point coordinates value, otherwise not as thresholding excessively
Target exports；
Calculation is divided into two steps：
(1) output quantity of detection is converted into binary number, quantitative relationship is：
Here N indicates 512；
|xi| indicate the modulus value size after FFT, γiIndicate threshold value.I.e. modulus value is denoted as 1 more than thresholding, and modulus value is not above
Thresholding is denoted as 0.
(2) quantification impulse is accumulated within N1 period, if quantification impulse accumulative total m in N1 period,
The number of the declaration of will of K accumulative 1, the point for crossing thresholding are denoted as 1, above whole flow process indicate a cycle, each
Period counts the primary coordinate for crossing threshold point, crosses thresholding and indicates 1, do not had to be exactly 0, continuously counts N1 period.It is previous
A period with regard to one be worth, now have to N1 period add up after, meet condition can just export height value.
After binary system accumulation, when there are many points for meeting the requirements thresholding simultaneously, only selection exported thresholding
First peak point mainly considers that maximum to test ride vehicle aircraft degree of danger is the object nearest apart from test ride vehicle
Body, so being not to look for all maximal peak points for crossing thresholding, but select first peak value for crossing thresholding；
In step 2, if the peak coordinate that linear frequency modulation sawtooth wave FMCW first crosses threshold point in channel 1 is p1_
Fmcw, the data after corresponding FFT transform are a_p1+1j*b_p1, and phase isWherein：A indicates the roads I
Data value, b indicates that the data value on Q roads, a_p1 indicate in the array that a+j*b form, the corresponding seat of peak point of mistake thresholding
It is designated as p1, a_p2 is indicated in the array that a+j*b is formed, and the corresponding coordinate of peak point for crossing thresholding is p2, and b_p1 is indicated in a+
In the array of j*b compositions, the corresponding coordinate of peak point for crossing thresholding is p1, and b_p2 is indicated in the array that a+j*b is formed, and is moved into one's husband's household upon marriage
The corresponding coordinate of peak point of limit is p2.
The peak coordinate that constant frequency wave CW first crosses threshold point is p1_cw, if linear frequency modulation sawtooth wave FMCW the in channel 2
One peak coordinate for crossing threshold point is p2_fmcw, and the data after corresponding FFT transform are a_p2+1j*b_p2, phaseIf the location point for crossing thresholding is equal to 1, then it is assumed that it is DC component, not as target discrimination；
The method of beat frequency value for calculating sawtooth wave band is：In channel 1, linear frequency modulation sawtooth wave FMCW, mistake
The coordinate p1_fmcw of the point of threshold point amplitude maximum, according to following rule, then the corresponding beat frequency value of the point is fb,
The rule is：
If this obtained crosses the number of the point of threshold point amplitude maximum, meet 1≤p1_fmcw≤256, in corresponding points
Beat frequency valuefsIndicate the size of systematic sampling rate；
If the maximum number of points p1_fmcw obtained, 256 p1_fmcw≤512 ＜, the beat frequency value in corresponding points
The method for calculating the Doppler frequency value of the constant frequency section is：In channel 1, constant frequency wave CW crosses threshold point amplitude most
The coordinate p1_cw of big point, it is f to calculate the corresponding Doppler frequency of point according to following ruled；
Rule is as follows：
If doing 512 points of FFT transform,
Count x, meets 1≤x≤256, judges gtoal setting, the Doppler frequency in corresponding points
Count x, meets 256 x≤512 ＜, judges that target is separate, the Doppler frequency in corresponding points
S3. it calculates the beat frequency value of sawtooth wave band, the Doppler frequency value of constant frequency section, relative velocity, calculate relatively
It is one or more in distance value, calculating deflection.
As a kind of technical solution, the method for calculating the relative velocity is：According to the Doppler frequency being calculated
Value fd, the speed v of target is calculated, calculating speed formula isWherein, c is the light velocity, c=3 × 108, frequency centered on f, f
=24.125GHz.
The method for calculating the relative distance value is：The Doppler frequency value f being calculated according to constant frequency sectiond, and saw
The beat frequency value f that tooth wave band obtainsb, the distance R of target is calculated, calculating range formula isWherein, T is
Period, T=10ms, B are modulating bandwidth, B=200MHz.
By by channel 1 and channel 2, phase calculation its phase difference that linear frequency modulation sawtooth wave band calculates separately,
According to calculation formulaObtain phase difference ψ；
According to angle calculation formula,Calculate the orientation angles of target, wherein d is antenna spacing, λ
For radar wave wavelength.
As a kind of technical solution, the method further includes step S4. filter trackings, and predicts next measurement time
Distance and velocity amplitude.
When anticollision millimetre-wave radar system completes relative velocity to simple target, relative distance in short distance anti-collision system
And it after corresponding azimuthal solution process, needs to be filtered tracking module.Since system output Refresh Data rate is fast,
The variable quantities very little such as distance and speed in very short time, can approximation see uniform motion as, predict next measurement time
Distance and velocity amplitude etc..Tracking and the premise and basis that prediction technique is adaptive tracing tracking filter.Main method is current
Have, linear autoregression filtering, Wiener filtering, Weighted linear regression, alpha-beta is filtered with alpha-beta-γ, Kalman filtering and simplification
Kalman filtering etc..
The present invention recommends to use α-βfilter.Since α-βfilter is relatively more uniform suitable for tracking error rate of change
The case where, so substantially suitable test ride vehicle flying scene.
In α-βfilter, the predictive equation of the constant gain filters is X (k+1/k)=Φ X (k/k), and filtering equations are
X (k+1/k+1)=X (k+1/k)+K [Z (k+1)-H (k+1/k)], wherein X (k/k) is the filter value at k moment, and X (k+1/k) is
The k moment, Z (k) was the observation at k moment to the predicted value at next moment.
When moving equation uses constant velocity model, constant gain matrix K=[α, β/T]T, state-transition matrixThe measurement matrix of this model is H=[1,0].α-βfilter is exactly to meet long gain matrix K, and state shifts square
Battle array Φ and measurement matrix H is respectively the constant gain filters of above-mentioned expression formula description, i.e.,
The selection of parameter alpha and β in α-βfilter has the response of tracking, convergence rate and tracking stability
Relationship.Generally require 0 ＜ α ＜, 1,0 ＜ β ＜ 1.In engineering, the value of α and β can be calculated according to formula, i.e.,WithFor wherein k for number, α and β as the variation of k takes different values, reality is in use, this
Two parameters can tend to definite value.
Target velocity, the distance settled accounts to single by α-βfilter can realize filter tracking and prediction.It can be with
The tracking of target is better achieved, while making the data of output more smooth, reduces the appearance of exceptional value, it is effective to improve system
The stability of system.
AD-FFT- thresholdings-resolving is usually used in existing signal processing method, inside this new processing method,
It increases AD- and removes direct current-adding window-FFT- thresholdings-binary system accumulation-resolving-predicting tracing.More more links.Especially
Direct current and binary system is gone to accumulate prediction and tracking.
Go the benefit of direct current：Since DC data can raise neighbouring threshold value, near DC, there are targets in this way
Data
When carrying out Threshold detection, there are certain interference, so can effectively improve target by the way of removing direct current
Detection probability.
The benefit of adding window：Hanning window or hamming window etc. are selected, secondary lobe is reduced, to improve the detection performance of target；The Chinese
Peaceful window can cause main lobe to be widened and reduce, but secondary lobe can be substantially reduced.
Benefit is accumulated using binary system：The point of limit of can making to move into one's husband's household upon marriage more is stablized, and is unlikely to thresholding between certain points
It knock-ons, improves the reliability of system.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope of present disclosure, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
