Description
Technical field
The invention belongs to shooting range measurment technical field, relate to especially the vertical target testing arrangement of a kind of infrared laser that is suitable for round-the-clock test and Flight Projectile and the method for testing of target position coordinate and speed.
Background technology
In the production of conventional Weapon and development, having much testing arrangement and methods about muzzle velocity and position, is all important underlying parameter test for the test of muzzle velocity and position for bullet, explosive or firearms.For the isoparametric measurement of bullet coordinate, at present both at home and abroad main light curtain target cross method of testing, sky cross method of testing, line array CCD cross method of testing, the array laser sensor testing method etc. of adopting.The cross detection sky of test macro of sky adopts optical fiber to converge and adopt the design of single circular light fulgurite received energy conventionally, the shortcomings such as this mode exists detectivity lower, deficiency and project organization complexity that the detection of large target surface bullet information is seemed.What cross test macro utilization due to sky is the detection principle using visible-light detector as core cell, and this mode is subject to the impact of natural environment very large, and when sky illumination is not enough, test macro cannot be worked.In research both domestic and external, proposed to utilize strip splicing array photoelectric receiving device to improve its detection performance, obtained certain effect, but its detection performance still cannot be improved in background low-light level one end on high, cause sky to still have certain limitation in one end of low-light level, to four light curtains and the six light curtains system that crosses, its oblique light curtain more seems not enough in one end of low-light level sensitivity especially.Researched and proposed in addition the design design sky that adopts out of focus technical measures to eliminate detection blind area, but also there are many deficiencies in this scheme in actual applications, as detection circuit because of splicing junior unit photoelectric device more, the ambient noise of stack is also large, in analog amplify circuit, be difficult to eliminate, its movable diaphragm adopting is eliminated the impact of illumination change, the shake of existence activity diaphragm causes false triggering, the problems such as bullet signal trigger point is inconsistent, if detection range is too high, need to change long focal length lens, making to act on visual field reduces, easily produce the possibility of test leakage, and structure is relatively complicated.In addition, at the sky of outdoor application, due to the special test of model bullet, need to extend to and carry out night, the existing sky test macro that crosses cannot be tested at night, forced the test macro that need to also can normally work at night.For adapt to low-light (level) or night environmental testing, have and researched and proposed the method for designing that adopts light curtain target, light curtain target is the detecting devices that adopts active light source to design, it utilizes array transmitting and receives pipe design, in test zone space, form the light curtain structure of a frame-type, this method for designing is when little target surface, measuring accuracy is higher, but along with target surface increases, structural design is also more difficult, transmitting is also poorer to the alignment of pipe with reception, when particularly many light curtain targets cross installation and debugging, it is this that to pipe, calibration is also more difficult to operation, to large target surface system (being greater than 1.5m*1.5m target surface), its certainty of measurement worse and worse.There is researcher to invent various light curtain targets, patent CN89102652, CN200620134458.7, CN200420007418.7, also have target range large area is used at home XGK-91-I type light screen target for velocity measurement and XGK-2002 type light curtain target, above light curtain target adopts the method for light source direct projection receiving system, and namely light source and receiving system are arranged in the both sides of formed light curtain.When adopting four light curtain targets or six light curtain targets to build four light curtains and the vertical target test macro of six light curtains, the light curtain target of this structure is difficult to guarantee the geometric angle of each light curtain target light interlude, is also not easy measure geometry angle value.
Multiple improved light curtain target method for designing has been proposed in patent CN1614348A, CN101403592A and CN1046975A, but there is defect for speed, the coordinate parameters measurement of large caliber weapon bullet in light curtain target, as speed and position measurement in middle trajectory and terminal ballistics position, because the target surface of light curtain target is little, if aim bias is easy to damage equipment.Laser light curtain target is also a kind of light curtain target, and its core is the detector formation detection target surface that adopts array Emission Lasers and accept the same band, also has same limitation.In order to improve the performance of light curtain target, in patent CN101943549A, proposed to adopt the design principle of a word line source and speculum, form the round-the-clock detection velocity-measuring system of frame-type.In patent CN202649229U, invention has designed the large target surface light screen target for velocity measurement of a kind of laser reflection formula, this light curtain target has adopted the array light source of three optical lens splicing view fields and 7 type structures to form and has surveyed light curtain, cost compare is high, because light-source structure is large, the luminous tube quantity of array is many, and power consumption, up to upper kilowatt, makes the in use shake due to power supply that the performance of some luminous tube be there are differences in lasting electric power system, cause false triggering, stability compares poor.Line array CCD Intersection Measuring System, what adopt due to it is the camera principle that crosses, the impact that camera imaging quality is subject to environment is very large, one end of high brightness on high, there is saturated phenomenon in camera, in low-light level one end, be difficult to identification echo signal, outdoor, be also difficult to realize the test of round-the-clock coordinate position.
