| 摘 要： | 利用运动单平台截获固定辐射源的信号、通过测向方法对其定位是电子对抗领域的基本问题之一,而定位误差的克拉美-罗限(CRB)是衡量该方法性能的重要手段。在研究CRB估计的基础上,得出了简化的CRB估计计算,分析了定位精度、定位收敛时间等指标与平台距离、速度、路径、测向误差等因素的关系。理论推导与仿真结果比较是一致的。

| Abstract: | It is a critical problem to locate a stationary emitter using a single motion platform through direction measurements,and the Cramer-Rao bound of positioning error is a main parameter to describe the performance.Here the estimation of CRB is discussed,and a simplified expression is derived.Based on this,an analysis of the relationships between the positioning precision,convergent time,with the factors such as platform distance,velocity,length of path,measurement error of direction,is presented.These relationships are in accordance with the simulation results. |
