10504 针对无人机进场阶段失去推力后,如何使其跟踪一条给定进场路径这一特殊情况,提出了一种3维Dubins路径跟踪方法。 After losing thrust in unmanned aerial vehicle (uav) approach phase, how to make it to track a given approach path this special cases, this paper proposes a 3 d Dubins path following method.
10505 该方法首先利用Dubins曲线解决无人机故障位置任意性及其路径求解实时性高的路径规划问题;‭ This method first, Dubins curves are used to solve unmanned aerial vehicle (uav) fault location arbitrariness and its path to solve the high real-time path planning problem;
10506 然后为了跟踪所生成的3维Dubins路径,设计了一种基于切换平面的自适应非线性制导方法,其中切换平面用来解决圆弧制导与直线制导之间的过渡问题,而自适应规则降低横纵向制导律之间的相互影响,从而提高了系统的跟踪精度。 ‭Then in order to track the generated 3 d Dubins paths, designs an adaptive nonlinear guidance method based on the switching surface, the switching surface is used to solve the problem of the transition between the arc guidance and linear guidance, and the adaptive rule reduced the mutual influence between the transverse longitudinal guidance law, so as to improve the tracking precision of the system.
10507 最后通过仿真实验验证了该方法的有效性。 ‭Finally, simulation results verify the effectiveness of the proposed method.

10509 该算法首先利用解析振速与声压信息,重构接收数据,求出协方差矩阵,并提取信号子空间第一列的3个分矢量进行孔径扩展。 The algorithm firstly using analytic vibration speed and acoustic pressure information and refactoring receiving data, and the covariance matrix, and trust the room space vector for three points in the first column of the aperture extension.
10510 然后,利用类单块拍条件下的矩阵重构得到3个新矩阵并合并。 Then, using the class under the condition of single block on matrix reconstruction got three new matrix and merge.
10511 最后,套用奇异值分解的多重信号分类算法得到目标波达方位估计。 Finally, apply singular value decomposition of multiple signal classification algorithm to get the target doa estimate direction.
10512 分析表明,所提算法利用数据的组织形式使信号矩阵对角化,最终恢复了矩阵的秩,而且具有一定的孔径扩展能力。 Analysis show that the proposed algorithm using the organization form of the data signal matrix diagonalization, eventually restored matrix rank, and have certain ability of aperture extension.
10513 同时,所提算法矢量阵阵列流形所具备的方向因子可以在模糊角度处形成抑制,保留了矢量阵的单边指向性。 At the same time, the proposed algorithm for vector of column has the direction of the manifold factor in fuzzy Angle formation inhibition, retained the vector array of unilateral directivity.
