| Abstract: | As narrow-beam high-gain phased array antena requires high precision beam pointing, the influence of installation error on beam pointing can not be ignored. The measurement method of installation based on optical aiming is proposed. The content of optical measurement and error correction matrix are given. Flight test shows that this method can reduce the beam pointing error caused by installation error, which is of great significance for high beam pointing accuracy. |
