摘要
为了提高复杂电磁环境下无人机着陆引导系统的抗干扰能力,可在无人机着陆段采用基于激光的无人机精确引导方法。本文对激光相对引导系统的工作原理及流程进行了分析,设计了基于激光引导的无人机着陆试验流程,并基于某无人机平台完成了试飞验证,获得了重要的试验数据,最后将激光相对引导数据与差分GPS引导数据统一转换到地平坐标系下,完成了两种体制的数据比较和误差分析,并进一步梳理了将激光相对引导技术推向工程应用需要注意的问题。
In order to improve the anti-jamming ability of the UAV guidance system in complex electromagnetic environment,a precise guidance method based on laser is used in the landing phase of UAVs.In this paper,we analyze the principle and process of the laser relative guidance system.Further,we design the landing test process of UAVs based on the laser guidance.The flight test is carried out on a scaled UAV platform and the important test data are obtained.Finally,we convert the laser relative guidance data and the differential GPS guidance data into the ground-level coordinate system,and the data comparison and error analysis of the two systems are completed.We further sort out the problems that need to be considered when the laser relative guidance technology is applied in practice.
