摘要
分析了红外目标源辐射强度随距离和时间的变化。在不同红外源强度的条件下,进行了红外源强度对红外系统输出信号的响应定标。同时,在激光辐照功率67W和辐照时间460ms条件下,用1.06μm连续ND:YAG激光对不同红外源强度下红外系统输出信号的干扰效果进行了对比实验。结果表明:激光对红外系统的干扰效果与红外目标源的强度成反比。当红外源强度在红外系统工作的线性范围时,激光对红外系统的干扰效果最明显。
Intensity of IR source varying with time and probation distance is analyzed. Under different IR source intensity, the output signal of IR system induced by IR source radiation is saled.The comparison experiments of IR source intensity influence on laser interference effects on the output signal of IR system are carried out using Nd: YAG laser irradiation.The laser output power is 67W and output duration is 460ms ae selected. Results show that the effects of laser interference on IR system is opposite to IR source intensity. The most obvious interference effect is realized when IR source intensity lies in linear operation range of IR system.
