摘　　要：拒止环境下的作战能力是当下无人机等作战平台的研究重要方向之一,在强拒止环境中,基于卫星定位与惯导的组合导航系统将无法有效地运行,通过平台自身携带的载荷提供的探测信息能够保障导航系统维持一定的作战能力,本文基于光电和SAR雷达的景象匹配定位信息对惯导进行修正,提出了一种在拒止环境下可有效改善导航系统的速度、姿态等精度的方法,并通过实验仿真,验证了所提方法的有效性。The operational capability in denied environment is one of the current important research directions for combat platforms such as unmanned aerial vehicles(UAVs).In environment characterized by high level of denial,integrated navigation systems based on satellite positioning and inertial navigation will not be able to function effectively.By utilizing the detection information provided by the payloads carried by the platform,the navigation systems can maintain a certain level of operational capability.This paper proposes a method that can effectively improve the accuracy of velocity,attitude,and other critical parameters of the navigation systems in denied environment by correcting the inertial navigation system based on the scene matching positioning information from the electro-optical equipment and synthetic aperture radar(SAR).The effectiveness of the proposed method is verified through simulation test.
