作为精确打击**系统的重要组成部分，红外跟踪系统主要用于在 运动载体上对目标进行搜索、识别、瞄准和跟踪。载体扰动会对红外跟踪系统的性能产生影 响，因此需要隔离扰动和消除扰动对跟踪的影响。通过对红外成像系统的原理进行研究，查 找出了可能造成红外图像扰动的因素，定性分析了扰动对设备造成的影响，最后为设备使用中如 何克服扰动影响提出了建议。

As an important part of a Precision Guided Weapon (PGW) system, the infrared tracking system is mainly used for search, recognition, aiming and tracking on a moving carrier. Because the perturbation of the moving carrier has effect on the performance of the infrared tracking system, it is necessary to isolate the perturbation so as to eliminate its effect on tracking. By studying the operation principle of the infrared imaging system, the factors which might cause infrared images to be perturbed are found. The effect of perturbation on an infrared tracking system is analyzed qualitatively. Finally, some suggestions on how to overcome perturbation when the infrared tracking system is used are made.
