中文摘要:

      为了解决动基座传递对准中航向角估计困难的问题，提出了基于光学测角和无线数据传输技术的传递对准技术方案。通过对航母舰体挠曲变形模型的建立和对光学测角原理的分析，构建了相应的卡尔曼滤波器。仿真结果表明，利用卡尔曼滤波能够估计出姿态误差角和光学测量装置自身的等效零偏。当对光学测量装置的等效零偏补偿之后，航母在匀速航行条件下，姿态误差和速度误差都可以得到快速的收敛，其中航向角误差可以在4 s内收敛到0.7′以内，明显提高了子惯导航向角的对准速度。

英文摘要:

      To solve the problem that it is difficult to estimate the heading angle by using traditional alignment on moving base，the transfer alignment based on optical angle measurement and wireless data transmission technology is put forward.Through the establishment of flexural deformation model of aircraft hull and analysis of optical angle measuring principle，the corresponding Kalman filter is built.Simulation results show that the attitude error and the equivalent zero bias of the optical measuring machine can be estimated by Kalman filter.After the equivalent zero bias of the optical measuring device is compensated，the attitude error and speed error can be fast converged when the movement is uniform speed.The attitude error can converge to 0.7′ within 4 s，the speed of the heading angle alignment is improved significantly.
