摘要
介绍了采用 TE2 1 模跟踪器 ,和、差通道单独配置低噪声放大器的单信道多模角跟踪系统 ,简述了自跟踪原理 。
The article introduces a mutil model single channel angle tracking system with TE 21 model coupled device and low noise amplifiers allocated respectively to the sum channel and the difference channel.The simple principle of tracking system is stated and the major parameters to influence the function of the system are analysed.
