| Abstract: |
| For the problem of tracking interruption caused by azimuth angle jump when the spherical phased array antenna is tracking the dynamic target with high elevation angle zenith pass,a zenith pass tracking method based on the rotation of coordinate system is proposed.The simulation results show that this method can meet the requirements of phased array antenna angle tracking design and effectively solve the problem of spherical array antenna tracking over the top with high elevation angle.The proposed scheme has been successfully applied in engineering projects. |
