| 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。
