摘要
组网雷达中通过协方差交叉进行目标定位可以提高目标定位精度,首先从理论上对多雷达数据融合定位精度进行了误差分析,提出了一种可应用于工程实践的提高目标定位精度的算法。该算法利用多部雷达协方差交叉缩小目标定位误差,使目标定位精度得以提高。仿真数据及工程实践验证了它的正确性及合理性,在雷达组网工程中也得到良好的应用。
Target location accuracy is improved by covariance intersection in radar network. This paper first provides an error analysis on the multi-radar data fusion target location accuracy, and then presents an algorithm that can improve the target location accuracy in the engineering practice. The algorithm decreases the target location errors by multi-radar covariance intersection. The correctness and usefulness of the algorithm is tested in the simulation data and engineering practice.
