摘要:
为改善光电探测靶的探测性能,研究了光电探测器对光幕区中弹丸红外热辐射能的获取,分析了幕厚、弹丸长度、弹丸辐射面积、大气衰减与光幕区弹丸红外热辐射特性的关系。采用将弹体划分为多个小面元的方法,建立了弹丸红外热辐射计算方程。研究了光电探测器的弹体红外热辐射通量计算方法。根据红外热辐射大气衰减理论,分析了不同波长光电探测器获得的弹丸红外热辐射能与大气透过率的关系,并计算了光电探测器在不同幕厚和作用距离下获得的弹丸红外热辐射能。结果表明:当探测距离一定时,弹丸作用于光幕的表面红外热辐射能与光电探测器接收辐射能成正比;当弹体长度与幕厚相等时,光电探测器获得的信号最强;距离越远大气的红外透过率越小,探测灵敏度越低;3~5μm波长光电探测器可获得最佳弹丸红外热辐射能。
Abstract:
To improve the detection performance of an optic-electric detection target,the energy of the projectile infrared heat radiation in screen gained by the optic-electric detector is studied.The relations of screen thickness,projectile length,projectile radiation areas and atmospheric attenuation between the infrared heat radiation performances of projectiles in screen are analyzed.The calculation equation of the projectile infrared heat radiation is established by parting the surface areas of projectiles to many small units.The calculation method of the projectile infrared heat radiation flux of the optic-electric detector is studied.According to the theory of the atmospheric attenuation of the infrared heat radiation,the relation between the projectile infrared heat radiation energies gained by optic-electric detectors with different wavelengths and atmospheric transmittances is analyzed,and the infrared heat radiation energies that the optic-electric detector gains under different screen thicknesses and detection distances are calculated.The results show: the projectile infrared heat radiation acting on the screen is proportional to the gained radiation of optic-electric detectors with the same detection distance;the output signal that the optic-electric detector gains is the strongest when the length of projectiles is equal to the screen thickness;the detection sensitivity decreases with the increase of the distance because of the decrease of the infrared transmittance;the projectile infrared heat radiation is the best when the detector wavelength is 3 ~5 μm.
