摘　　要：激光捷联惯导广泛应用于导弹、舰船、飞机和火箭等,我国目前对其在大过载、大角度锥动以及线角振动等高动态环境下的性能研究相对不足。针对激光捷联惯导在高动态环境下精度下降的问题,从惯性器件、减振、算法等角度梳理了激光捷联惯导动态误差机理和提高动态精度的关键技术,选取介绍了近年来有价值的研究进展,简要探讨了未来提高激光捷联惯导动态精度的思路。Laser strapdown inertial navigation is widely used in missiles,ships,aircraft and rockets.At present,there is a lack of research on its performance in high dynamic environment such as large overload,large angle coning and linear angular vibration.Aiming at the problem of the accuracy decline of laser strapdown inertial navigation in high dynamic environment,the dynamic error mechanism of laser strapdown inertial navigation and the key technologies to improve the dynamic accuracy from inertial devices,vibration reduction and algorithm are summarized in this paper.The valuable research progress in recent years is introduced,and the ways to improve the dynamic accuracy in the future are briefly discussed.
