Hood type target simulator
Technical field
The present invention relates to a kind of hood type target simulator, belong to the infrared technique field.
Background technology
Precise guidance attack weapon is subjected to the various countries military extensively to be favored.In future war, the attack precision that weapon is attacked in precise guidance may play crucial effects to the transformation of whole war situation situation, and therefore, each main military country all attacks weapon in the precise guidance of positive development precise guidance.Infrared guidance is used more extensive in precision guided weapon, the performance that when development and detection infrared guidance weapon, needs the infrared homing system of tester, when the infrared homing systematic function of test, adopt simulator to simulate the mode that the infrared target source is a kind of convenient and efficient.
Summary of the invention
The hood type target simulator that the purpose of this invention is to provide a kind of radiation intensity, radiation variable size is in order to detect infrared homing systemic-function.
For achieving the above object, the present invention adopts following technical scheme: a kind of hood type target simulator comprises head-shield and is arranged at head-shield interior tumbler and Optical devices; Has the stationary conduit that matches with nose of missile to be detected in the described head-shield, described tumbler comprises the automatically controlled turntable of the axis process stationary conduit axis that is fixed in the output shaft on the head-shield, be fixed with on the output shaft of automatically controlled turntable along the axially extended gripper shoe of stationary conduit, this gripper shoe is provided with position, angle platform away from an end of output shaft, this position, angle platform is positioned at the side of gripper shoe towards stationary conduit, described Optical devices are fixed on the platform of position, angle, these Optical devices comprise parallel light tube and are fixed in the outer black matrix of parallel light tube, this black matrix is used for to the parallel light tube infrared radiation, and the infrared radiation exit at black matrix is provided with the adjustable diaphragm dish, the axis of described parallel light tube and the axis coaxle of stationary conduit.
The arranged outside of described stationary conduit import department has clip.
Described parallel light tube adopts Cassegrain's formula optical system.
Described automatically controlled turntable is the worm gear electric rotary table.
The target seeker position marker of the output shaft of described automatically controlled turntable and guided missile to be detected is coaxial.
Be provided with tumbler in the hood type target simulator of the present invention, this tumbler has pitching and these two kinds of forms of motion that swing on horizontal plane, and Optical devices are installed on the tumbler and with tumbler and move.When Optical devices moved with tumbler, the infrared spectral range that Optical devices are radiated the weapon head can change accordingly.In addition, be provided with the adjustable diaphragm dish, can regulate Optical devices by adjusting grating dish and penetrate ultrared intensity in the infrared radiation exit of Optical devices black matrix.As seen, this hood type target simulator can be simulated radiation intensity, radiation size, can be used for detecting the target-seeking performance of infrared guidance weapon to different radiation intensity, radiation size target.Also have, the target seeker position marker of the output shaft of automatically controlled turntable and guided missile to be detected is coaxial, has saved the operation with required target and guided missile aligning like this, has simplified the inspection step, has improved checking efficiency.

The specific embodiment
Shown in Fig. 1,2,3,4; hood type target simulator of the present invention comprises head-shield 1; the front portion of this head-shield 1 is provided with stationary conduit 3; this target simulator is fixed on the head of guided missile 5 by stationary conduit 3; the shape of this stationary conduit 3 is consistent with the profile of guided missile 5 front ends; can better be secured to the head of guided missile 5 like this; in addition; being bonded with fabric in stationary conduit 3 protects the body surface to avoid scratching; also have; arranged outside at stationary conduit 3 opening parts has clip 4, head-shield 1 and body can be connected together closely by this clip 4.In head-shield 1, be installed with tumbler 6, this tumbler 6 comprises a worm gear electric rotary table 9, the axis of the output shaft 10 of worm gear electric rotary table 9 is through the axis of stationary conduit 3, and with the axis normal of stationary conduit 3, and the target seeker position marker of the axis of output shaft 10 and guided missile to be detected is coaxial.On output shaft 10, be installed with one along the axially extended gripper shoe 8 of stationary conduit, this gripper shoe 8 is provided with position, angle platform 7 away from an end of output shaft 10, realize elevating movement by position, manual adjustments angle platform 7, realize swinging of horizontal direction by worm gear electric rotary table 9.On position, angle platform 7, be installed with Optical devices 2, these Optical devices 2 comprise a parallel light tube based on Cassegrain's formula, the arranged outside of this parallel light tube has a black matrix 11, black matrix 11 is used for infrared radiation in parallel light tube, infrared radiation mouth place at black matrix 11 is provided with an adjustable diaphragm dish 12, has the different aperture in aperture on the adjustable diaphragm dish 12, by regulating the position of adjustable diaphragm dish 12, infrared ray is penetrated from the aperture of different diameters, the ultrared energy that penetrates in the aperture in different apertures is different, therefore, can simulate the infrared target of different radiation intensity.The infrared ray that Optical devices are sent by black matrix 11 forms spot light through the aperture on the adjustable diaphragm dish 12 and outwards disperses, after level crossing 17 reflections, incide on the secondary mirror 16, reenter through the light of secondary mirror 16 reflection and to be mapped on the principal reflection mirror 13, infrared ray forms directional light after principal reflection mirror 13 reflections, project by infrared window 15 on the target seeker of guided missile.In parallel light tube, also be provided with drier 14 and guarantee drying in the parallel light tube, one side of parallel light tube top drier is provided with observation window, can whether lose efficacy from the agent 14 that sees drying of this observation window 20, and can open the bonnet of parallel light tube after drier 14 lost efficacy and change drier.
