| 摘要: |
| 当飞行器被一个几何位置已知的雷达跟踪时，相对方位与仰角可用安装在飞行器上的角传感器来测量，相对高度数据可用无线电或激光高度表来获得。根据这些数据即可确定飞行器的位置。为提高定位精度，使用了扩展的卡尔曼滤波器，得到的位置参数被变换成射面坐标系。用计算机模拟的结果是良好的。 |

| Application of Extended Kalman Filtering to Passive Location Aided with Height Data |

| Abstract: |
| When the vehic1e is tracked by a radar with known geometrical position，the relative bearing and elevation can be measured by angle sensor installed on the vehic1e，and the relative height data can be obtained by radio or laser altimeter. According to these data，the vehic1e position can be determined. In order to raise the accuracy of position location，Extended Kalman Filter is utilized. The obtained position parameters are transformed to the flight path plane coordìnate system，The results from computer simulation are satisfactory. |
