| 摘要: |
| 针对“速度+姿态”匹配方案运算量大、鲁棒性差和“角速度+加速度”匹配方案存在的杆臂效应难以补偿的问题,提出了“速度+姿态矩阵”快速传递对准匹配方案,给出了对准模型．仿真结果表明,在载机做简单角机动的情况下该方案即可完成对准过程并取得较高精度,为机载武器提供了一种具有实用价值的传递对准方案．在机载主惯导和精确制导武器的子惯导系统都采用捷联惯导的大趋势下,捷联系统特有的数学平台特点将促使“速度+姿态矩阵”匹配模式具有更为广阔的应用空间． |

| Abstract: |
| Velocity-attitude matrix” matching method is proposed as a new approach to transfer alignment, in allusion to the disadvantages of “velocity-attitude” method which has a huge computation and low robustness, and “angular rate-acceleration” method which has a difficulty to compensate the lever-arm effect, and then an alignment model is deduced. Simulation results show that this method can complete a high precision alignment process and achieve a high precision, even if carrier aircraft do simple Angle maneuver. With the development tendency of SINS(strap-down inertial navigation system) as both master INS and slave INS, the characteristics of mathematics platform in SINS will make “velocity-attitude matrix” method used more and more widely. |
