Continuous rotation north-finding algorithm based on constrained adaptive Kalman filter

As an orientation measurement system,north-finder has been playing a significant role in both military and civilian fields of orientation and control.In this paper,to deal with drawbacks in the conventional north-finding systems,a dynamic strategy based on continuous rotation modulation to measure the rotational angular velocity of the earth is proposed.By modeling the dynamic error,optimizing the process constraint and estimating dynamic noise,a method combining delay compensation and hardware adjustment,and a constrained adaptive Kalman filter(CAKF)algorithm are designed for the north-finding strategy.According to simulation and experiments,the proposed algorithm can achieve the high-precision north-finding with robust and anti-noise performance.

状态转变增强拉曼光谱(英文)

表面增强拉曼散射(SERS)是公认的超灵敏的光谱工具。和传统的优化SERS基底材料或构筑完美的结构策略相比,我们提出了一种极其简单和灵敏的方法,该方法被命名为状态转变增强拉曼光谱(STERS)。这种STERS检测方法可广泛的应用于毒品安全检测、食品安全和环境保护等方面。如果我们把这种方法和便携式拉曼光谱仪结合,这种应用将得到更加广泛的拓展。
