一种用PN码校正相控阵天线通道误差的新方法
A New Method of Calibrating Phased Array Antenna Using PN Sequence
摘要
Abstract
In order to calibrate the amplitude-phase error of phased array antenna and achieve more accurate performance of digital beamforming, this paper provides a calibration method based on the pseudorandom ( PN) sequence. In this method, pseudorandom sequence is used as the calibration test signal and the cali-bration can be proceeded at the same time as communication. The PN sequence is sent by a calibration sta-tion and received by the antenna, and passes the channals in which amplitude-phase error exists. At the re-ceiving terminal, the local codes correlate with the received signal and calculate the calibration vector. The simulation results show that this method can calibrate the amplitude-phase error of phased array antenna.关键词
