Description
Technical field
The present invention relates to field of measurement, rotation target and application process thereof that particularly a kind of virtual space target is separated.
Background technology
At present, the domestic tracking performance that generally adopts rotation target virtual space target measuring optical measuring equipment.Optical measuring apparatus just requires to possess certain tracking performance when observing measurement motion of celestial body, rocket launching, guided missile track, such as the angular velocity of following the tracks of, angular acceleration, tracking accuracy, anti-other target interference etc.Electro-optical tracking device all need be done the simulated target tracking test at their tracking performance of indoor detection before dropping into formal the use.When target rotated, electro-optical tracking devices such as astronomical telescope were with the mode tracking target from motion tracking, and the miss distance of enforcement record object, calculate indexs such as tracking velocity and tracking accuracy according to data recorded.
The rotation target of domestic normal employing does not now also possess the function that the virtual space target is separated, jamming target is provided, and it is imperative therefore to develop a kind of rotation target and application process that can the virtual space target separates.
Summary of the invention
In order to solve the problem that exists in the prior art, rotation target and application process that the present invention provides a kind of virtual space target to separate can effectively improve the indoor tracking performance test of photoelectric tracking measuring equipment.
It is following that the present invention solves the technical scheme that the prior art problem takes
The rotation target that a kind of virtual space target is separated, this target comprises: support, rotary axis, rotary seat, catoptron and light source, this target also comprises: target generator; Target generator comprises: parallel light tube, decide target, moving-target and moving-target drive unit; Catoptron, target generator and light source are fixed on the rotary seat, and rotary seat is connected with rotary axis, and the two cooperation relatively rotates, and rotary axis is fixed on the support; The front side of deciding target is fixed on the image planes position of parallel light tube, and moving-target is installed in decides the target rear side, and the moving-target drive unit is connected with moving-target, and the two cooperates relative motion.
The rotary target target application process that a kind of virtual space target is separated, this method comprises the steps:
Step 1: tested photoelectric tracking measuring equipment is placed under the rotary seat, and the tracking axis of adjustment photoelectric tracking measuring equipment is an intersection point, and the light of mirror reflects can be incided on the intersection point of photoelectric tracking measuring equipment;
Step 2: adjustment rotary target target rotary axis, make the amount angular velocity rotation of rotary seat according to tested photoelectric tracking measuring equipment, the photoelectric tracking measuring equipment moves with the rotation target with automatic tracing mode;
Step 3: the rotation of moving-target drive device drives moving-target separates the virtual space target, thereby detects the tracking performance of photoelectric tracking measuring equipment.
Principle of work of the present invention: light source irradiation is decided target so that rotary target target fixed target to be provided, and the photoelectric tracking measuring equipment moves with rotary seat after catching fixed target.Arbitrary position in the rotary seat motion process can make to occur a plurality of targets in the photoelectric tracking measuring equipment tracking field of view through the incision of moving-target drive device drives moving-target.Except that fixed target keep the origin-location constant, all the other targets are moved out with certain relative velocity outside the visual field, thus the virtual space target is separated.
Beneficial effect of the present invention: the present invention have simple in structure, cost is low, simple operation and other advantages, can remedy the industry blank.
