水下高速运动目标运动分析有其特殊性,其一即为本舰不允许进行机动,故单阵纯方位目标运动分析不适于分析水下高速运动目标,本文基于双阵方位测量值分析其运动状态。纯方位目标运动分析是典型的非线性估计问题,文中利用扩展卡尔曼滤波算法进行双阵纯方位目标运动分析,从而解算出目标运动要素。文章通过数值仿真分析算法性能,验证了该方法的有效性。 Underwater high-speed moving target motion analysis has its own particularity. The first one is that this ship is not allowed to maneuver, so the single-array purely azimuth target motion analysis is not suitable for analyzing underwater high-speed moving target. Based on the double array azimuth measurement, status. The purely azimuth target motion analysis is a typical nonlinear estimation problem. In this paper, the extended Kalman filter algorithm is used to analyze the bi-directional target movement and solve the target motion components. The article analyzes the performance of the algorithm through numerical simulation and verifies the effectiveness of the method.
