According to the fuse detection device, pulse laser fuse detection is adopted, the fuse detection device has confidentiality and anti-interference performance as the laser has good monochromaticity, the locating accuracy of fuse is largely increased as the laser has good directionality, and the sensitivity of the fuse is increased as the laser has high luminance, and therefore the fuse detection device has good anti-electromagnetic interference capability, working safety, reliability and high ranging accuracy, and is widely applied in the aviation field.
Description
Technical field
The invention belongs to laser fuze technical field, be specifically related to a kind of fuze test based on based on pulse type laser range measurement principle.
Background technology
Laser fuze is a kind of sniffer, and for guided missile or other weapons, whether the detection of a target when with target intersection enters in the hazard boundary of weapon.Laser fuze has that positioning precision is high, resolution ratio is high and the feature such as anti-electromagnetic interference capability is strong.
In Chinese patent bulletin CN201583211U (patent No. is 200920299191.0), disclose " a kind of laser fuze ", the utility model relates to a kind of laser fuze, and object is to reduce the false-alarm probability of laser fuze.A kind of laser fuze, comprises optical transmitting system, radiating circuit, information-processing circuit, receiving optics, receiving circuit, laser instrument and detector, it is characterized in that: it also comprises polarizer.The utility model adopts polarizer, and the laser that laser instrument is sent changes complete linearly polarized light into by partial poolarized light; The mode that adopts analyzing to receive receives the light energy of and vertical both direction parallel with utilizing emitted light polarization direction simultaneously, has reached the effect of identifying metal target from natural background.
What existing laser fuze generally adopted is to determine height to draw fried mode, and the distance between laser fuze measurement target and guided missile reaches preset value, sends and draws fried signal.If exist near by target of attack the natural background similar to target size as Minor Construction, bushes, little tree etc., laser fuze first detects can send equally and draws fried signal, generation miss bomb affects the attack effect of guided missile.
Summary of the invention
Fuze test based on pulse type laser range measurement principle is mainly made up of parts such as power supply, laser instrument, optical transmitting system, receiving optics, detector and pulse amplifier, signal processing and decision circuits.Use the test of pulse type laser fuse, because the monochromaticjty of laser is good, make it have Secret anti-interference performance; Good directionality makes again the positioning precision of fuse greatly improve; Brightness height has improved the sensitivity of fuse, thereby has good anti-electromagnetic interference capability, safe and reliable and range accuracy is high, gets a lot of applications at aviation field.
The aforesaid fuze test based on pulse type laser range measurement principle, wherein, the receiving system on the emission system of this equipment and receiving system and bullet and emission system form an optical circuit.
The aforesaid fuze test based on pulse type laser range measurement principle, wherein, the emission system of this equipment transmitting tool there are certain requirements the laser of frequency and energy, and with the form of light beam to space radiation light energy, form required detection viewing field in space, provide synchronizing signal simultaneously.
The aforesaid fuze test based on pulse type laser range measurement principle, wherein, the receiving system of this equipment mainly completes the judgement of detection to target reflection laser, echo signal and provides detonator signal.Signal processing system is the core of whole test macro, complete output pulse sampling, filtering, echo pulse signal shaping amplify, matched filtering, pulse interval measurement, pulse width measuring and range gating, the logic judgement etc. carried out in order to suppress interfering signal, the target echo signal that last basis receives calculates the height apart from target.
Advantage of the present invention and beneficial effect are that influence fuse is mainly divided into two kinds of electronic fuse and optical fuzes.Radio proximity fuse is because its electric wave signal is easily discovered by the other side and intercepts and captures, and poor anti jamming capability, causes positioning precision low, the accurate control of the best fried point of impact.And for the fuze test based on pulse type laser range measurement principle, because the monochromaticjty of laser is good, make it have Secret anti-interference performance; Good directionality makes again the positioning precision of fuse greatly improve; Brightness height has improved the sensitivity of fuse, thereby has good anti-electromagnetic interference capability, safe and reliable and range accuracy is high, gets a lot of applications at aviation field.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the fuze test based on pulse type laser range measurement principle.
Specific embodiments
The invention will be further described with reference to the accompanying drawings below.
As shown in the figure, laser instrument is the important composition parts of laser fuze test, requires the laser of the laser instrument transmitting of testing equipment to have identical frequency with laser instrument on bullet.At 6 TCH test channels (6 quadrant) of certain model fuse test, the fuse launch window on bullet is outwards Emission Lasers pulse constantly.The receiving system of equipment receives light pulse after tested, is converted into the electric pulse of certain frequency.Testing equipment receives by serial line interface the test command that signal processing system is sent, on selected TCH test channel, receive the electric pulse through detection system conversion, and after the time delay control of a pulse period, the target echo signal of simulation is sent into the corresponding emission system of testing equipment.That is to say the laser works of this respective quadrants in testing equipment, transmitting with fuse same frequency but have the laser pulse of certain delay, is sent to the receiving system on bullet.Send into sequential and the number of the echo impulse of fuse receive window by control, and detect the output state of fuse product, turn-key system can be realized the performance test to fuse product.The self check of equipment utilizes its 6 tunnel to receive/send out the corresponding relation in channel design, forms one group respectively send out/receive lane testing pair by a certain launch window receive window relative with it.The a certain launch window of self check control command control by signal processing system is launched the pulse signal of some, on corresponding receive window, should be able to receive corresponding pulse signal.Send out/receive the pulse number of passage by comparison, can detect the duty of testing equipment, complete the self check of testing equipment.
