直升机平台背景磁干扰小信号模型求解与补偿
Helicopter Platform Background Magnetic Interference Small Signal Model Solving and Compensation
摘要
Abstract
For helicopter external high precision magnetic survey pod detection platform,platform background magnetic interference mechanism is analyzed,and concluded that platform background magnetic disturbance consists of the aircraft cartier magnetic disturbance,fluctuating magnetic interference caused by pod swing and the magnetic disturbance caused by fluctuating track of platform.Magnetic survey pod trajectory calculation model and platform background magnetic interference small signal model are established.And combining with the characteristics of platform motion,small signal model solving method is given.Through simulation and calculation,the magnetic interference small signal model is verified,and the analysis results show that using the small signal model to solve and compensate the magnetic disturbance is completely possible,the adaptability is very good and magnetic disturbance compensation rate can reach more than 90％.关键词
