两舰协同定位误差分析的研究

Research on Cooperative Locating Error between Two Ships

多平台侦察信息协同定位具有一定的超视距作用,测向交叉定位技术是协同定位使用较广泛的方法。根据两舰在不同基线、不同测向精度对海、空目标探测的误差几何稀释度GDOP(Geometric Dilution of Precision)分布图的仿真进行协同定位误差分析的研究,从而确定定位精度,进行协同定位。

The synergy locating with reconnaissance information on multi-platform has certain over-the-horizon effect. The direction finding locating technology is widely used in the co-location. Through the simulation of the GDOP（geometric dilution of precision） distribution in the target detection at sea and in air with different baselines and different measurement accuracies of two warships, the locating errors are analyzed. Then the synergistic positioning accuracy is determined and the cooperative locating is proceeded.
