摘要
基于巡航导弹末制导中的景象匹配辅助导航技术,采用蒙特卡罗仿真方法,通过抗重复模式实验、抗视角变换实验和抗噪性实验,研究了影响景象匹配性能的主要因素的变化趋势,为景象匹配区的选择提供了有力依据。仿真所得匹配性能优于高斯理论预测结果。
In the terminal phase of cruise missiles,scene-matching aided navigation is one of key technologies to improve its attacking precision.A large number of Monte Carlo simulations are aim at the matching performance against similarity pattern,performance against viewpoint transaction,and performance against noise.Then,it is discussed that some important factors which influence the scene-matching performance.The results show that the acquisitions probability from simulation is better than that by theoretical approximation.Therefore,the simulation gives beneficial evidence to select the scene-matching area.
