| 摘 要： | 通过人工红外照射改变目标与背景的红外辐射特性能够对相关跟踪形成有效干扰,其中,红外照射的位置对干扰效果具有重要影响。为提升红外照射干扰相关跟踪的效率,文中建立了红外照射仿真搜索相关跟踪干扰点模型,对干扰相关跟踪的有效照射位置进行快速搜索。首先,运用TracePro光线追迹软件建立了真实实验条件下的红外照射系统模型,并利用高斯模型对照射光斑的照度分布进行了拟合。然后,在一定空间范围内,采用二维扫描的方式进行真实照射干扰和仿真照射干扰对比实验,结果表明:仿真照射与真实照射的干扰结果一致性达到了98%,且仿真照射找出了真实照射条件下干扰相关跟踪的全部干扰点,从而很好地验证了文中方法的有效性。

| Abstract: | Artificial infrared irradiation has an effective interference on correlation tracking by changing the infrared characteristics of target and background, where the location of infrared irradiation has an important impact on the interference performance. In order to improve the interference efficiency, the model of searching interference points by using infrared irradiation simulation was established. First, the infrared irradiation model in the true experimental environment was built in TracePro and the illuminance distribution of irradiation spot was fitted by Gaussian model. Then, the experiments with true irradiation condition and simulation irradiation condition were carried out. The comparison experiments show that the interference results of different irradiation locations under the two conditions are uniform in 98% and all interference points are found by irradiation simulation, illustrating the effectiveness of the proposed method in the paper. |
