摘要
在分析低轮廓"动中通"跟踪系统关键技术及天线稳定跟踪和波束跟踪的基础上,给出一种陀螺稳定跟踪和复合跟踪联合工作的模式。其中陀螺稳定跟踪考虑了由于温度和时间引起的偏移误差问题;复合跟踪在陀螺稳定跟踪的基础上加入了一维机扫一维电扫的波束跟踪方法,并给出了波束跟踪的理论和Matlab仿真结果。该联合跟踪的方法能够在保证跟踪精度的前提下有效降低系统成本,对低轮廓"动中通"跟踪系统的研究设计具有实际意义。
A method which inosculates the gyro steady tracking and hybrid tracking was proposed after a prior discussion of the key technology antenna stabilization and beam tracking in the tracking scheme of multi-planar antenna SOTM. The correction of offset error due to temperature drift and time drift was introduced in the gyro steady tracking. And the hybrid tracking include the gyro steady tracking and beam tracking which with elec- tronic tracking in direction and mechanical tracking in azimuth direction, the academic analysis and Matlab simulation result was given. The tracking scheme can provide accurate tracking but low cast. It is aimed to the beneficial for studies and designs of servo system of multi-planar antenna SOTM.
