摘要
Abstract
The antenna tracking function is the foundation for the vehicle satellite communication on the move( SOTM) to offer wireless communications,and the phased array antenna can provide better tracking performance,but the beam scanning range is limited. In order to realize the phased array antenna tracking in the entire orientation,a method using phased array antenna and servo is presented. The data processing flow of algorithm is provided, and the prototype has been developed. According to the prototype working principle,the formula to calculate the tracking angle error is given. The test result matches with the calcu-lating result,and the signal-to-noise ratio(SNR) loss is smaller than 0. 5 dB at the angle speed between (57. 88~115. 76)./s.关键词
