摘要
研究了一种红外点源目标模拟器.该目标模拟器采用光谱滤光片对黑体发出的光波进行过滤,得到3~5μm波段的红外辐射;改变光栏孔的直径,模拟不同大小的目标;控制中性密度滤光片的不同透射比部分进入光路,得到不同辐射强度的目标,动态地控制目标红外辐射强度;转动方向镜控制目标在导引头视场内的位置,模拟目标的运动,实现了对红外目标运动特性的模拟.实验结果表明,该红外点源目标模拟器实现了对3~5μm波段红外动、静态目标的模拟,满足了某红外半实物仿真系统的实际需要.
A novel infrared target simulator with radiation spectrum in the range of 3/μm to 5 μm was developed and demonstrated. The simulator could imitate the infrared target in different sizes and different distances from observer. The spectral filter was used to filter the radiation emitted from the light source other than the spectrum in the range of 3 μm to 5 μm. Controlling the rotation of the field stop could imitate the target of different sizes and controlling the transmissivity of neutral density filter could realize different energy density radiation. The target movement within the field of view of infrared seeker was simulated by rotating the direction mirror. The test result shows that the infrared target simulator can simulate the infrared target with radiation spectrum in the range of 3 μm to 5 μm and satisfy the needs of an infrared hardware-in-the-loop simulation.
