| 摘 要： | 研究了采用长基线干涉仪(LBI)体制的运动单平台无源定位系统受平台姿态抖动影响的问题，指出由于平台姿态的快速无规则变化，相位差变化率(RPDC)方法将难以适用，应当采用目标方位角变化率参数进行定位。基于此，针对三维几何空间，提出了一种RP-LS方法估计目标方位角变化率，继而实现对目标的定位。仿真结果表明，该方法能有效解决LBI体制运动单平台定位系统对姿态抖动的适应问题，实现对目标的快速高精度定位。

| Abstract: | The influence on the location performance of the attitude vibration of a moving observer,which utilizes a long baseline interferometer(LBI)structured passive location system,is discussed.Because of the vibration,the rate of phase difference change(RPDC)method is not feasible any more.The parameters of rate of DOA changes should be adopted.A range parameterized least square(RP-LS)method is proposed to estimate the rate of DOA changes and locate the emitter under the 3-D circumference when the attitudes vibrate.Simulation results show that this method is effective to deal with the problem of attitude vibration of the LBI structured passive location system of a single moving observer. |
