Description
Technical field
The present invention relates to ranging technology, especially relate to a kind of being avoided that and detect geo-stationary object and produce the thunder of error
Reach timesharing detection mesh calibration method.
Background technology
Traditional radio detection technology has ultrasonic ranging, infrared distance measurement, laser ranging, radar range finding etc..Ultrasound
Away from the ultrasound wave launched, owing to different material is different with absorbance to the reflectance of ultrasound wave, for the material that absorbance is high
Echo-signal may None-identified；The hidden danger that laser ranging existence safe to the human body is certain, and the difficulty made is relatively big, cost is relatively
Height, and optical system needs to keep clean, otherwise impact is measured；The shortcoming of infrared distance measurement is that precision is low, and range finding is near, direction
Property is poor；Radar range finding substantially a kind of frequency electromagnetic waves is launched and reception technique, also exists relatively between target and radar
When position is moved, target echo frequency will change, and the knots modification of frequency can calculate the translational speed of target, but thunder
Reach the accuracy when detecting the object of geo-stationary and the most often do not reach requirement.
Summary of the invention
For overcoming the shortcoming of prior art, detection geo-stationary object produces to present invention aim at providing one to be avoided that
The radar timesharing detection mesh calibration method of raw error.
The present invention is realized by techniques below measure, and a kind of radar timesharing detection mesh calibration method, described radar is installed
In a driving means, its method comprises the steps:
A. move detection, after driving means drives radar to make it with the motion that remains a constant speed with installing, radar emission detection letter
Number after barrier reflects, received reflected signal working the scheduled time by radar；
B. static detection, driving means quit work make radar with install keep static after, radar emission detection signal
After barrier reflects, received reflected signal by radar and work the scheduled time；
C. motion detection and static detection forked working.
As a kind of optimal way, also comprise the steps: that d. is collected according to motion detection and stationary motion detection
Data carry out algorithm process, will process after data feedback return, calculate the distance of barrier.
As a kind of optimal way, change movement velocity and/or the direction of motion of driving means, carry out motion detection with quiet
Only detection.
As a kind of optimal way, change the scheduled time, carry out motion detection and static detection.
As a kind of optimal way, include to described installation car, ship or the aircraft in motion.
As a kind of optimal way, described driving means is motor.
As a kind of optimal way, the described scheduled time is less than 10 seconds.
The present invention controls driving means by software and drives the motion and standstill time of radar, moves the scheduled time, static
The scheduled time, circulate back and forth；During driving means drives radar movable, when testee (driving vehicle as front and back)
With radar install (vehicle of radar is installed) moving with direction at a same speed, then detected object is the most relatively
Being static with installing in radar, during at this moment motion detection, radar can detect target object well, and when static detection
Radar can detect to move well installs the barrier on ground in radar, the timesharing that present invention introduces detection, the sound of employing rule
Over-over mode, and alt time is extremely short, it is thus possible to detect the barrier in various speed exactly, it is to avoid detection geo-stationary
Error during object.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention radar motion speed and time coordinate figure.
Detailed description of the invention
Below in conjunction with embodiment and compare accompanying drawing the present invention is described in further detail.
A kind of radar timesharing detection mesh calibration method, with reference to Fig. 1, described radar is arranged in a driving means, its method
Comprise the steps:
A. move detection, after driving means drives radar to make it with the motion that remains a constant speed with installing, radar emission detection letter
Number after barrier reflects, received reflected signal working the scheduled time by radar；(such as 1 second, this time controlled at 10 seconds
In)；
B. static detection, driving means quit work make radar with install keep static after, radar emission detection signal
After barrier reflects, received reflected signal by radar and work the scheduled time；
C. motion detection and static detection forked working, can carry out motion detection successively and carry out static detection again, it is possible to
First carry out static detection and carry out motion detection again.
This method controls driving means by software and drives the motion and standstill time of radar, moves the scheduled time, static
The scheduled time, circulate back and forth；During driving means drives radar movable, when testee (driving vehicle as front and back)
With radar install (vehicle of radar is installed) moving with direction at a same speed, then detected object is the most relatively
Being static with installing in radar, during at this moment motion detection, radar can detect target object well, and when static detection
Radar can detect to move well installs the barrier on ground in radar, and the timesharing that this method introduces detects, uses the sound of rule
Over-over mode, and alt time is extremely short, it is thus possible to detect the barrier in various speed exactly, it is to avoid detection geo-stationary
Error during object.
In a radar timesharing detects the embodiment of mesh calibration method, the most all right on the basis of previous technique scheme
Also to comprise the steps: that d. carries out algorithm process according to motion detection and the data that collected of stationary motion detection, will at
Data feedback after reason is returned, and calculates the distance of barrier.
In a radar timesharing detects the embodiment of mesh calibration method, the most all right on the basis of previous technique scheme
It is to change movement velocity and/or the direction of motion of driving means, carries out motion detection and static detection.Can be in a direction
After motion certain time, then adverse movement, it is returned to initial position and the effect of multiple relative velocity detection contrast reaching radar
Really, it is also possible to make radar be returned to initial position at the interval of the most repeatedly cross detection.
In a radar timesharing detects the embodiment of mesh calibration method, the most all right on the basis of previous technique scheme
