| 摘 要： | 雷达跟踪低空目标时,由于多路径传播的影响,目标俯仰角的测量会出现测量误差.并且由多路径传播引起的测量噪声方差较大,在时间上具有相关性.应用交互多模(IMM)算法来提高跟踪低空目标的性能,并且提出了一种去相关的滤波方法来克服多径误差相关性的影响,最后给出了计算机仿真的滤波结果.

Tracking Low Elevation Targets with the Interacting Multiple Model Algorithm |
| |
| Abstract: | In the context of tracking low elevation targets with radar,the multipath propagation would cause acute errors in the elevation angle measurement of the targets.And the measure errors with larger variance are correlated in time.To improve the performance of tracking low elevation targets,the Interacting Multiple Model(IMM) algorithm is proposed in this paper.And a simple decorrelation process is presented due to the correlation of the measure errors.At last the computer simulations based on several scenarios show the performance of the algorithm. |
