为在较短时间内规划出性能指标最优的攻击轨迹、提高飞行器作战效能,研究一种基于改进分布估计算法的二维航迹规划方法。引入坐标变化和候选节点,针对采用分布估计算法进行问题求解容易陷入局部收敛的缺点,提出模拟退火的分布估计算法,其退火温度以信息熵表示。
In order to plan the attack trajectory with the best performance index in a relatively short period of time and improve the combat effectiveness of the aircraft, a two-dimensional trajectory planning method based on the improved distribution estimation algorithm is studied. In order to solve the problem that the distribution estimation algorithm is easy to fall into local convergence, the distribution estimation algorithm of simulated annealing is proposed. The annealing temperature is expressed by information entropy.
