摘要: 该文在现有单站无源定位方法的基础上,介绍了相位差变化率定位法。该方法利用观测平台上两个相互正交的相位干涉仪接收目标辐射电磁波的相位差获取目标的方向信息,利用对应的相位差变化率获取目标的径向距离信息,从而实现对目标的实时高精度定位,文中给出了观测平台飞行姿态角固定情况下的定位表达式并进行了定位精度分析。仿真结果表明,该方法是一种发展前途较好的单站无源定位方法。Abstract: In this paper, the single observer-passive location method using phase difference change rate is introduced based on existing methods. The direction of the target can be obtained with phase difference between two orthogonal interferometers on the observer and the radial distance with corresponding phase difference change rate. Then the target can be located with high speed and precision. Locating expressions are given when the observer is flying with a fixed posture angle. Simulations show that this method is effective.
