摘 要:针对机载航炮可攻击区求解问题,提出改进回溯法并应用其进行机载航炮可攻击区的研究。首先,根据直升机机载航炮攻击区的定义,综合考虑直升机和机载航炮的数学模型,基于最小二乘法预测目标轨迹,并针对空对地目标打击问题建立瞄准命中方程。然后,考虑武装直升机和航炮的约束条件,将可攻击区求解问题转化为空间树优化问题,引入剪枝函数和搜索优先级函数,提出改进回溯法对机载航炮可攻击区边界进行求解,略去了可攻击区内部冗余节点的搜索,提高了攻击区搜索效率。最后,通过仿真验证了所提方法的可行性和有效性。In order to solve the problem of airborne gun attack area,this paper proposes an improved backtracking method and applies it to the study of airborne gun attack area.First,according to the definition of attack area of helicopter airborne guns,the mathematical models of the helicopter and the airborne gun are comprehensively considered.The target trajectory is predicted based on the least square method.And the aiming hit equation is established for the air to ground target attack problem.Second,considering the constraints of armed helicopters and air guns,the problem of solving the attack area is transformed into a space tree optimization problem.The pruning function and the search priority function are introduced.An improved backtracking method is proposed to solve the boundary of the attack area of airborne air guns.The search of redundant nodes inside the attack area is omitted.And the search efficiency of the attack area is improved.Finally,the feasibility and effectiveness of the proposed method are verified by simulation.
