| 摘 要： | 建立了某型卫星制导炸弹在大气层内制导飞行的弹道模型,探索了求解多目标可投放区(LAR)的技术途径,给出了具体的求解策略.在分析和比较国内外LAR计算方法优劣性的基础上,针对传统模拟搜索法收敛速度慢的缺点,提出了一种改进的快速搜索算法.该算法利用射程多项式拟合模型为变步长模式搜索法提供搜索初值,最大限度的降低迭代次数.算...

| Abstract: | A three degrees of freedom(3-DOF) trajectory model for a certain satellite-guided bomb within the atmosphere is built.Then,the methods to solve multi-target launch acceptable region(LAR)are systematically analyzed.Based on the analysis for calculation accuracy and efficiency,a polynomial fitting model is introduced and an improved fast pattern search algorithm is developed for searching the boundary of LAR.The algorithm starts with an approximate initial value obtains from a polynomial fitting function,and can quickly converges toward the extreme value because the initial value is very close to it.The simulation results show that the algorithm is better than the traditional algorithm.Finally,a target set is selected to calculate the multi-target LARs under different initial delivery conditions. |
