摘要
Abstract
In the process of real-time communications between high-speed motion platforms such as aircraft,missiles and a repeater satellite,the postures of platforms change all the time,which affects the quality of communication seriously.For keeping communications with the satellite,the phased array antenna on them must aim at the direction of satellite all the time.The design of angle tracking system is given,and the key functions of the system are introduced.For the rectangular array with symmetrical and uniform characteristics,by studying and improving the traditional theory of monopulse angle measurement and Kalman filter,an angle tracking algorithm based on sum-difference angle measurement and adaptive α-β filtering is proposed.Through simulation,the angle measurement and tracking precision is given,and the factors affecting the system tracking precision is analysed.关键词
