Abstract
The invention discloses a downward-looking tracking testing method for an electro-optical targeting system and a testing device for implementing the method. The testing device comprises a two-dimensional rotary table. A collimator is assembled on the two-dimensional rotary table, and an installing part used for fixing the position of the electro-optical targeting system is arranged above the collimator. The installing part is assembled on a rack. According to the downward-looking tracking testing method for the electro-optical targeting system and the testing device for implementing the method, the relative motion between the collimator and the electro-optical targeting system is achieved through the mode that the two-dimensional rotary table drives the collimator to motion, and thus the movement of the electro-optical targeting system relative to a target source is simulated; in the process, a collimated light source emitted from the collimator always faces upwards, so that a view field blind area does not appear in the electro-optical targeting system above the collimator; particularly, when the downward-looking performance of the electro-optical targeting system to a target in the position under the system needs to be tested, the electro-optical targeting system can be placed in the position over the collimator, at the moment, the position between the collimator and the electro-optical targeting system is not subjected to interference from the two-dimensional rotary table, and hence the downward-looking tracking performance test scope of the electro-optical targeting system is expanded.
Description
Technical field
The testing arrangement of tracking test method and enforcement the method is looked under the present invention relates to a kind of EOTS.
Background technology
At present, after laser guided weapon thrown in by the operational aircrafts such as transporter, bomber, unmanned plane, helicopter, Airborne Electro-Optics Sighting System needs to keep the tracking to target, guides for laser guided weapon provides to irradiate.Because laser guided weapon is mostly unpowered, weapon throws in rear flying speed lower than carrier aircraft, therefore often occurs the demand of looking tracking under EOTS carries out target.Like this when carrying out tracking capability test to EOTS, just must test depending on tracking performance under EOTS.Under existing EOTS depending on tracking capability test process be: EOTS is fixed on dimensional turntable, parallel light tube is installed in the side of dimensional turntable, thus drive EOTS to carry out pitching and orientation adjustment, with the target of the cursor analog photoelectricity sighting system side-lower of parallel light tube by dimensional turntable.But need with immediately below the cursor analog photoelectricity sighting system of parallel light tube during target, the receiving terminal of EOTS can be vertically downward, now the visual field of EOTS can be subject to the important actor interference of dimensional turntable, cause EOTS cannot observe the cursor of parallel light tube, also the tracking capability test that existing testing arrangement can only realize in limited pitching scope is just made, when the angle of pitch is more than a threshold value, cylinder due to dimensional turntable cannot be kept the tracking to target to blocking of system sight line, occur testing blind zone.
Summary of the invention
The object of this invention is to provide a kind of increase the EOTS of test specification under look tracking test method, present invention also offers simultaneously and be a kind ofly exclusively used in the testing arrangement implementing to look tracking test method under this EOTS.
In order to realize above object, the technical scheme of looking tracking test method in the present invention under EOTS is as follows:
Look tracking test method under EOTS, comprise the steps:
Step one, is arranged on parallel light tube in dimensional turntable, EOTS to be tested is placed in the top of parallel light tube, and by regulating parallel light tube and/or EOTS, makes parallel light tube be in immediately below EOTS or side-lower;
Step 2, EOTS keeps motionless, drives parallel light tube motion by dimensional turntable.
In the present invention, the technical scheme of testing arrangement is as follows:
Testing arrangement, comprises dimensional turntable, dimensional turntable is equipped with for the parallel light tube as target source, and above parallel light tube, be provided with the installing component for fixing EOTS position, and installing component is assemblied in frame.
Dimensional turntable comprise rotary table base and on to rotate the orientation frame of assembling around the vertical axis extended, be equipped with between orientation frame and parallel light tube for driving parallel light tube transverse-moving mechanism along the direction movement of vertical orientations frame pivot center on orientation frame.
Transverse-moving mechanism comprises the traversing guide rail be fixed on orientation frame and the guide type shoe be connected with parallel light tube, and guide type shoe coordinates along track length direction guiding movement with traversing guide rail.
Traversing guide rail is the arc orbit of the axis bending around horizontal-extending.
Arc orbit is that two ends flush and middle low semicircle.
Parallel light tube is offset to the side of the rotation of orientation frame.
The guiding mechanism of the axis oscillating moved in the horizontal direction or around vertical extension is equipped with between installing component and frame.
Guiding mechanism comprise fixed pedestal and on longitudinal slide of longitudinally guiding movement assembling, longitudinal slide is equipped with the cross slide of transversely guiding movement assembling, described installing component is on cross slide.
The elevating mechanism for driving installing component to move up and down is equipped with between cross slide and installing component.
The present invention drives the mode of parallel light tube motion to realize the relative motion of parallel light tube and EOTS with dimensional turntable, thus simulation broadcasting and TV sighting system is relative to the movement of target source, in the process, the source of parallel light that parallel light tube is launched all the time upward, so that the EOTS above parallel light tube there will not be blind area, visual field, especially need testing photoelectronic sighting system to immediately below look performance under target time, can EOTS be placed in directly over parallel light tube, now can not be subject to the interference of dimensional turntable between parallel light tube and EOTS, thus under increasing EOTS, look the scope of tracking capability test, ensure that the abundant degree of test.
