Description
Technical field
The invention belongs to shooting range measurment technical field, particularly a kind of infrared laser being suitable for round-the-clock test founds the method for testing that target testing arrangement and Flight Projectile target position coordinate and speed.
Background technology
Having much about testing arrangement and the method for muzzle velocity and position in the production and development of conventional Weapon, 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, mainly adopt light curtain target convey measurment method, sky convey measurment method, line array CCD convey measurment method, array laser sensor testing method etc. both at home and abroad at present.The detection sky of sky convey measurment system usually adopts optical fiber to converge and adopts the design of single circular light fulgurite received energy, it is lower to there is detectivity in this mode, seems not enough and the shortcomings such as project organization complexity to the detection of large target surface bullet information.Due to the utilization of sky convey measurment system is using the detection principle of visible-light detector as core cell, and this mode is very large by the impact of natural environment, and when sky illumination is not enough, test macro cannot work.Proposed to utilize strip to splice array photoelectric receiving device in research both domestic and external and improved its detection performance, achieve certain effect, but its detection performance still cannot be improved in background low-light level one end on high, sky is caused to still have certain limitation in one end of low-light level, to cross system to four light curtains and six light curtains especially, its oblique light curtain more seems not enough in one end sensitivity of low-light level.Research and propose the design design sky adopting out of focus technical measures to eliminate detection blind area in addition, but also there is many deficiencies in actual applications in this scheme, as detection circuit because the junior unit photoelectric device of splicing is more, the ambient noise of superposition is also large, be difficult to eliminate in analog amplify circuit, its movable diaphragm adopted eliminates 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 too high needs changes long focal length lens, effect visual field is reduced, the possibility of easy generation 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, existing sky convey measurment system cannot be tested at night, forces the test macro needing also can normally work at night.In order to adapt to low-light (level) or night-environment test, there is the method for designing researched and proposed and adopted light curtain target, light curtain target is the detecting devices adopting active light source to design, it utilizes array emitter to design pipe with reception, the light curtain structure of a frame-type is formed in test zone space, 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, launching and receiving is also poorer to the alignment of pipe, particularly many light curtain targets cross installation and debugging time, this calibration pipe 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.The various light curtain target that had researcher to invent, patent CN89102652, CN200620134458.7, CN200420007418.7, the XGK-91-I type light screen target for velocity measurement also having target range large area at home to use 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 employing four light curtain targets or six light curtain targets build four light curtains and six light curtains found target test macro, the light curtain target of this structure is difficult to the geometric angle ensureing each light curtain target light interlude, is also not easy measure geometry angle value.
The light curtain target method for designing of multiple improvement is proposed in patent CN1614348A, CN101403592A and CN1046975A, but light curtain target is for speed, the coordinate parameters measurement existing defects of large caliber weapon bullet, as in the speed of intermittent ballistic and terminal ballistics position and position measurement, 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 adopting array emitter laser and accept the same band, also there is same limitation.In order to improve the performance of light curtain target, in patent CN101943549A, proposing the design principle of employing one wordline light source and speculum, forming the round-the-clock detection velocity-measuring system of frame-type.In patent CN202649229U, invention devises the large target surface light screen target for velocity measurement of a kind of laser reflection type, the array light source that this light curtain target have employed three optical lens splicing view fields and 7 type structures forms detection 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 in use because the shake of power supply makes the performance of some luminous tube there are differences in the electric power system continued, cause false triggering, stability compares poor.Line array CCD Intersection Measuring System, what adopt due to it is that camera crosses principle, 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 identify echo signal, be also difficult in outdoor realize the test of round-the-clock coordinate position.
