SINS空中初始对准滤波器的设计

论述了一种捷联惯导系统（ＳＩＮＳ）空中对准的方法，它通过适当地增加卡尔曼滤波器系统方程中的白噪声来补偿由模型简化而带来的系统噪声，并通过大幅度的机动来克服外界环境的干扰。仿真表明，它不仅能在较短的对准时间内获得高对准精度，而且对系统噪声和环境噪声有很强的鲁棒性。

DESIGN OF THE FILTER FOR INITIAL ALIGNMENT ON FLYING PLANE OF SINS

This paper discusses a new method of alignment on flying plane of SINS. It suitably adds white noises of the system equations of Kalman filter to compensate the system noises accompanying the simplification of model. At the same time,through the maneuver of the plane, it overcomes the disturbance of environment. The simulating test shows the high alignment accuracy can be acquired in short time and it has stronger robustness to the system noises and the measurement noises accompanying the simplification of model and the disturbance of environment.
