传统的单阵纯方位目标运动分析需要观测平台进行机动，复杂的海战环境下这往往是不被允许的，利用多维观测要素可以使得本舰在不机动的情况下实现对目标的运动分析，本文基于双阵纯方位进行目标运动分析。几十年来，基于双阵纯方位的目标运动分析技术层出不穷，但绝大部分方法都忽略了一些明显的先验信息，譬如距离速度等要素的数值范围。为解决这一问题，采用一种不等式约束条件下的无迹卡尔曼滤波器对目标状态进行估计，仿真和试验处理结果表明，该方法能提升收敛的速度和精度。
Maneuvering of the observation platform is required during bearings-only target motion analysis using single array , this would not be allowed in complex sea warfare environment, this paper utilizes bearings of two arrays to analyze the state of the target, and usually some known constraint information such as constraints of range and course, is ignored during target motion analysis, this is a waste of information, to avoid this phenomenon, this paper introduces an inequality constrained cubature kalman filter to estimate the state of the target. The effectiveness of the method is verified through simulation and the experiment.
