摘要
在航海舰船准确定位的研究中,多舰测向交叉定位是在复杂海战场环境下较为常用的一种被动协同探测方式。参与定位的舰艇布局对测向交叉定位的探测范围和定位精度具有重要影响,应根据作战任务和作战海区地理特点对舰艇布局进行优化。舰艇布局涉及了舰艇数量、舰艇间距和编队队形三个方面因素,如何进行合理配置是舰艇布局优化的难点问题。建立了多舰测向交叉定位误差的数学模型,对不同布局条件下的测向交叉定位误差分布进行了仿真。通过仿真结果的对比分析,得出不同定位需求和海区条件下舰艇数量、舰艇间距和编队队形的配置方法,从而实现舰艇定位布局的优化。
The muhi-ship DOA location is a common passive co-location method under the complex sea battlefield environment. The ship layout plays an important role on the detection zone and position accuracy of DOA location. Therefore the ship layout must be optimized on the basis of operational mission and geographic features of operational area. The ship layout includes three factors： number of ship, interval between ships and ship formation. How to configure the three factors with reasonable setting is the difficult problem of the ship layout optimization. The mathematical model of position error of the multi-ship DOA location is built. The position error distributions of DOA location under all kinds of layouts are simulated. By the comparison and analysis of the simulation results, the reasonable setting methods for the number of ship, interval between ships and ship formation under different location demands and sea areas are acquired, and so that the ship layout is optimized.
