When carrying out earth's surface elevation and finely detecting, first adjust the height of sliding support post 2, make the bilateral measurement slide rail 11 can
It is placed in above tested earth's surface with level or according to certain angle, and records slide rail 11 place plane and the angle on ground.So
After, detection scanner unit is put in slide rail 11, and adjusts slide rail 11 spacing, reach antenna and effectively support and can be smooth
The effect slided, it is ensured that during (radiating surface) may be stuck in slide rail 11 outside antenna bottom, and scanner unit can be made to slide smoothly.
Then, by moving detection scanner unit and recording its diverse location on slide rail, use point to survey an acquisition mode and enter
Row detection, obtains the vertical dimension away from earth's surface of the horizontal plane corresponding to each test point.
One, for measure slide rail be situation during level
Earth's surface measurement of higher degree auxiliary device is placed on elevation change earth's surface to be measured, is slided by regulation six and prop up
The length of dagger, makes slide rail 11 holding level, using the slide rail plane of earth's surface measurement of higher degree auxiliary device as detection interface.
When detection starts, scanner unit is placed in slide rail 0 graduation position and carries out first data acquisition, and by it
As demarcating road, in order to demarcate the zero time point (t of radar0) position.Concrete operations are as follows:
(1) scanner unit and vertical dimension d on earth's surface when demarcating road and starting to detect as shown in Figure 6, is measured0, root
According to aerial spread speed c of electromagnetic wave (c=3.0*103m/ns), radar return first arrival at fixed point can be calculated
Theoretical two-way travel time is tc=2d0/c(ns)。
(2) as it is shown in fig. 7, using primary peak position as ski-jump, read radar wave primary travel time t0, this time is
The theoretical two-way travel time t of echo first arrivalcSystem delay t when arranging with antenna system and parameterdSum, i.e. t0=tc+
td。
(3) system delay t is calculated according to above-mentioned relationd=t0-tc。
Owing to system delay is a change at random amount for change in little scope, it is required for carrying out during detection the most every time
Calculating to it, with the take-off time of calibration accuracy.
(4) as shown in Figure 8, after completing zero crossing time demarcation detection, radar parameter and the ground of scanner unit is kept
The state of table measurement of higher degree auxiliary device, carries out and carries out continuity point survey with △ S for interval along slide rail plane, it is thus achieved that S1, S2,
S3... SnFirst arrival t reflex time of measuring point1, t2, t3... tn, and correspondence deduct system delay t thereind, the most permissible
Obtain t between the real air primary travel time caused by the reflection of ground surface and interfacei' (i=1,2,3...n).Wherein:
ti-td=ti' (i=1,2,3 ... n)
(5) as it is shown in figure 9, according to t between air primary travel time1', t2', t3' ... tn' aerial with electromagnetic wave
Spread speed c, can calculate S1, S2, S3,……SnDistance d at surface distance detection interface corresponding to each test point1, d2,
d3... dn., wherein:
di=ti' * c (i=1,2,3 ... n)
Two, it is situation during θ for measuring the inclination angle between slide rail and horizontal plane
Relatively big at stratigraphic dip, slant range is bigger, it is impossible to meet measure by adjusting earth's surface measurement of higher degree auxiliary device
Slide rail is positioned at the condition of horizontal plane, then set up along dip direction direction by measurement of higher degree auxiliary device in antenna earth's surface, with earth's surface
The slide rail plane of measurement of higher degree auxiliary device, as detection interface, makes detection interface parallel with the approximation inclination angle on earth's surface, i.e. and lead to
Cross the compass 5 on framework 1 and measure the inclination angle theta on earth's surface.
When detection starts, equally scanner unit is placed in slide rail 0 graduation position and carries out first data acquisition, and
As demarcating road, in order to demarcate the zero time point (t* of radar under inclination measurement planar condition0) position.Concrete operations are such as
Under:
(1) measure the scanner unit when demarcating road and starting to detect and be perpendicular to distance d* on earth's surface0, exist according to electromagnetic wave
Spread speed c (c=3.0*103m/ns) in air, can calculate the radar return being perpendicular to slide rail at fixed point equally
First arrival theory two-way travel time is t*c=2d*0/c(ns)。
(2) using primary peak position as ski-jump, radar wave primary travel time t under inclination measurement planar condition is read
*0, this time is theoretical two-way travel time (t*c) and the antenna system of inclined reflection ripple first arrival and system time parameter arranges
Time delay (td) sum (t*0=t*c+td)。
(3) system delay t under inclination measurement planar condition is calculated according to above-mentioned relationd=t*0-t*c。
Owing to system delay is a change at random amount for change in little scope, therefore in the condition at inclination measurement interface
Under, each detection is also required for carrying out the calculating to it, with the take-off time of calibration accuracy.
(4) after completing zero crossing time demarcation detection, the radar parameter of scanner unit and earth's surface measurement of higher degree auxiliary
The state of device, carries out and carries out continuity point survey with △ S* for interval along slide rail plane, it is thus achieved that S*1, S*2, S*3... S*nTest
First arrival t* reflex time of point1, t*2, t*3... t*n, and correspondence deduct system delay t thereind, then can obtain by ground
T* between the real air primary travel time that surface and interface reflection causesi' (i=1,2,3...n), wherein:
t*i-td=t*i' (i=1,2,3 ... n)
(5) according to t* between air primary travel time1, t*2, t*3... t*nSpread speed c aerial with electromagnetic wave,
S* on tilt detection interface can be calculated1, S*2, S*3... S*nAt each point, interface distance tilt detection interface, earth's surface hangs down
Straight distance d1*, d2*, d3* ... dn*。
(6) in order to the detection interface that inclination angle is θ is corrected to higher than on a horizontal interface on earth's surface, such as Figure 10 institute
Show, except calculating this point (S* on tilt detection interfacei) distance ground surface interface vertical distance di* ' outward, in addition it is also necessary to calculate
This point is to vertical dimension S* on earth's surfaceDi.Under tilt detection boundary condition, owing to measuring point spacing is less compared with yardstick △ S*, permissible
Approximate uses di* d is representedi* ', i.e. in Figure 10 | S*iA | can approximate | S*i A'|。
Then S*iThe horizontal plane corresponding to the Dian correcting value away from ground surface and interface | di* real | for the d shown in figurei* ' and | S*Di
S*i| sum.
Because: | S*Di S*i|=| 0S*Di| tan θ,
|S*iA |=di*/cosθ
Then: di* real=| 0S*Di|tanθ+di*/cosθ
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, common for this area
For technical staff, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
