摘　　要：针对现有分布式多传感器系统中无法知道何时需要进行系统误差估计与配准的问题,采用基于与航迹相关的检验统计量研究系统误差的实时检测。首先,分析了分布式传感器系统中传感器系统误差对各传感器上报到融合中心的航迹的影响,在此基础上构建了系统误差实时检测的检验统计量,同时给出了检测的门限与准则,最后通过建立合适的仿真环境分析了在各传感器分别有无系统误差情况下的检测问题,并且通过实测数据进一步验证,仿真结果以及实测数据验证了检测算法的可靠性及实用性。Focusing on the problem that when should systematic errors need to be estimated and corrected in distributed multi-sensor system, real-time detection of systematic errors is studied based on track correlation test statistic error detection problem for. First, effects of systematic errors to tracks reported by each sensor at fusion center are analyzed. Based on this analysis, the test statistic of realtime detection of systematic error is given, while the detection threshold with criteria is also provided.Finally, appropriate simulation environment is built to analyze the detection of systematic errors in the case of each sensor has and / or hasn＇t bias. Further real data are used to test the performance of the detection algorithm. And simulation results and real data test results demonstrate the reliability and applicability of the detection algorithm presented in this paper.
