The victs antenna is a passive mechanical phased array antenna, and is particularly suitable for the field of satellite communication-in-motion antennas due to the characteristics of low profile, low power consumption, high g/t value and the like, but the signals sent by satellites are weak when reaching the victs antenna due to the fact that the victs antenna is far away from the satellites, and at the moment, the signal intensity angle received by the victs antenna can influence subsequent signal analysis.
At present, the method of polarization matching the transmitting angle of the satellite end and the receiving angle of the antenna end can increase the intensity of the antenna receiving signals, because the mode of transmitting signals at the satellite end is a broadcasting mode, namely a mode of transmitting signals to the periphery, the signal intensity when signals transmitted from different angles reach the antenna end is different due to the influence of the periphery environment, but the prior art only considers polarization matching and does not consider the influence of the maximum gain direction (the transmitting direction of the maximum signal intensity) of the antenna of the satellite on polarization matching, and secondly, the polarization matching in the prior art is realized by adjusting the transmitting angle and the receiving angle so that the transmitting angle and the receiving angle are consistent, but the angle adjustment of the antenna at the transmitting side comprises the angles of xyz, if the angles are artificially adjusted, the efficiency is too low, and a scheme capable of quickly and accurately adjusting the angles of the xyz is needed. Thus, the efficiency of the signal strength improvement associated with the VICTS antenna is insufficient.
