一种基于游标测距的火箭飞行特征事件判定方法
A Method for Judging Characteristic Events of Rocket Flight Based on Vernier Ranging
摘要
Abstract
In order to solve the problem that the telemetry data is easily affected by events and the optical image is easily affected by weather,this paper presents a method for judging the character-istic events of space launches by using external radar data.The method makes use of the feature e-vents when the vernier ranging will have a large measurement error,through the vernier ranging increment difference structure judgment basis,and the detection of its extreme point to complete the judgment.The measured data of eight launches of four types of rockets are experimentally ver-ified and compared with the telemetry data.The results show that the method can accurately detect characteristic events such as rocket stage separation and throwing fairing.The judgment time of stage separation is compared with the telemetry data,and the deviation is within 1 s.关键词
