摘　　要：针对常规兵器试验领域电视经纬仪测试同帧地面多炸点数据匹配交会计算问题,提出了一套完整的数据处理方法,该方法首先将各个测试站的角度数据进行全组合交会计算,得到众多可能炸点坐标数据集合,然后根据近邻法则,设定距离阈值,利用聚类思想剔除多数假目标,保留接近目标数量的可能炸点集群;将同一炸点集群的可能炸点数据进行算术平均,得到接近目标数量的初判的炸点位置集合;再根据证据理论思想,运用矩阵分析法对初判的炸点位置集合进行分析处理,最终得到炸点坐标数据集合。计算机仿真试验表明,此种方法能有效地处理电视经纬仪拍摄的小于或等于10个同帧地面炸点目标角度数据,得到炸点坐标。Aiming at the matching and intersection of multi-blasting point data tested with video theodolite in conventional ordnance test,it offers an entire set of analyzing data techniques.Firstly we made the all-combination intersection calculation with the angle data from each testing station to obtain the collection of coordinate data of many possible blasting points.Then we set the distance threshold value according to the near neighbor rule to get rid of the majority of fake objections by clustering method,and retained the possible blasting point collections closed to the target.Thirdly we processed the preliminary blasting points collections with matrix analysis based on the evidence theory.Eventually we got the collection of the coordinate data of blasting points.Simulation and experiment results show that the method can effectively process the angle data of no more than 10 ground exploding point targets with the same frame,and get the coordinates.
