大范围散布弹丸落点测量最优布站方法

Research on the Optimal Station Method of the Forward Intersection Measurement of the Projectile Drop Point

针对大范围散布弹丸落点测量优化布站问题,通过前方交会误差公式分析了影响弹丸落点测量布站的因素,指出传统上的最优交会角对布站的指导性不强,进而分析了弹丸散布和清场范围对布站的影响,建立了最优布站的优化模型。针对大范围测试的需要,根据弹丸落点服从不同分布,提出了采用区域内最小误差、最大误差和平均误差作为评价布站优劣的综合指标,并通过计算机模拟进行求解。提出了采用基线长度指导试前布站的方法,给出了任意散布和清场范围时的最优布站方法。

In this paper,the factors affecting the station distribution of the forward intersection measurement of the projectile drop point are analyzed through the forward intersection formula,which is pointed out that the traditional optimal intersection angle is not strong enough to guide how to distribute the measurement stations. Furthermore,the influence of prejectile dispersion and clearing range on the station distribution is analyzed and the optimal model for stations is established as well. Finally,the optimal station method for arbitrary spreading and clearing range is given that the closer the maearing station is to the projectile drop point.When the projectile falls a little on the distance,the measuring instrument and the theoretical drop point are approximated as an isosceles triangle. When the projectile is spread over a large distance,the ceorresponding optimal baseline length can be solved by the computer.
