靶场光雷测量数据融合定位方法研究及应用

在靶场测量中,光电经纬仪由于测量直观、可靠性好、测量精度高等特点,一直被作为外弹道跟踪测量的重要设备,但是其不具备单站定位功能且双站交会受布站等因素限制。针对这种情况,为充分利用测量数据,将部署在经纬仪附近的具有作用距离远的雷达系统与光电经纬仪建立联合定位模型。首先对雷达和经纬仪的测量数据进行时间和空间配准,然后通过单站定位方法得到目标的位置。应用结果表明,其定位精度明显优于雷达单站定位精度,该方法可以作为计算弹道坐标的一种补充。

Research and application on fusion photoelectric theodolite-radar measuring data

Photo-electric theodolite has always been used as an important measuring equipment in the range for its intuition,reliabilty and precision. However, mono-station locating is out of the question for a single theodolite and double-station intersection lacating is restricted by factors such as the arrangement of stations. In order to fully exploit the measuring dada, the paper sets up a joint-locating model by combining a theodolite with its neighboring radar system which bears a long operating distance. The model firstly aligns the data of a theodolite and the data of a radar-system in time and space,then aquires the location of the target, which serves as a supplement to the caculation of a trajectory. Applications show that the proposed model is feasible.
