摘要
天线上行组阵是空间功率合成技术中的重要应用之一,将极大提高天线远场EIRP值。重点对上行组阵中空间功率合成的性能进行理论分析和仿真验证。首先介绍了空间功率合成的基本概念、方法原理、主要优点;然后对天线上行组阵空间功率合成的理论进行了公式推导,并从天线远场方向图的角度进行了简要分析;最后通过Matlab软件对天线上行组阵空间功率合成性能进行了仿真,通过改变阵元个数或者调整天线间相位差,观察干涉条纹变化,可实现合成功率改变。仿真在理论上验证了天线上行组阵实现空间功率合成的可行性。
Antenna uplink array is one of the important applications of spatial power synthesis technology,which can improve the effective isotropic radiated power（EIRP） value of the far-field antenna greatly. The spatial power synthesis performance in the uplink array is conducted with theoretical analysis and simulation verification emphatically. The basic concepts,methods and principles,and the main advantages of the spatial power synthesis are introduced,then the theory of spatial power synthesis in the uplink array is deduced with formula,and analyzed briefly from the perspective of the antenna far-field pattern.The spatial power synthesis performance in the uplink array was simulated by Matlab software. The adjustment of the synthetic power was realized by changing the number of array element or adjusting the phase difference among antennas,and observing the changes of interference fringes. The simulation results prove that the feasibility of spatial power synthesis can be achieved by antenna uplink array in theory.
