摘　　要：研究人工光源对红外成像跟踪的影响对保证跟踪稳定性以及提高红外成像制导武器精度具有重要的意义。文章从红外成像跟踪系统的组成出发，详细分析了人工光源对视频信号处理、边缘跟踪以及相关跟踪的影响，并对不同光源照射参数时目标的跟踪效果进行了实验与分析，结果表明：人工光源照射目标时将影响成像跟踪的稳定性，当光源照射参数不同时，红外成像跟踪误差将不同，相同条件下，光照功率越大，照射距离越近时，跟踪误差越大，垂直照射比平行照射时的误差大。To study on the effect of the artificial illuminator on the infrared imaging tracker has an important meaning to keep the tracker＇ s stability and also to improve the imaging IR weapons＇ pre- cision. Beginning with the composing of the infrared imaging tracker＇ s system, the effect of the arti- ficial illuminator on video signal processing, edge tracking, correlation tracking is discussed in de- tail. The targets＇ tracking effect through different parameters is tested and analyzed. The results show that the imaging tracker＇s stability will be affected when the targets are illuminated by the artifi- cial illuminator. The infrared tracking error is different under different illuminators＇ parameters. In the same condition, the tracking error is greater when the illumination power is bigger and the distance is nearer. And the illumination error at the vertical direction is bigger than at the parallel direction.
