摘　　要：以同频抛物面天线阵列为研究对象,以单个抛物面天线口径满足远场条件为工作场景,对天线阵列进行了空间功率合成算法的模型搭建与仿真分析。在算法建模中,构建以正六边形天线阵列为发射天线组阵对象,将各发射天线视为点源,到达接收面的波束为平面波束,计算接收面上各点对应各天线波束与发射天线口径法线间的波束角,根据发射天线的极化方向与波束方向推导出接收点处的场强方向,并将场强矢量分解于三个坐标轴上,同时考虑天线场强的波动行程相位偏移,结合波动方程参与功率合成计算。最后,通过仿真对空间功率合成算法进行了验证,为空间功率合成研究提供一种新的方法。This paper focuses on co-frequency parabolic antenna arrays,using the aperture of a single parabolic antenna meeting far-field conditions as the working scenario.It involves constructing and simulating an algorithm model for spatial power combining within these antenna arrays.In the algorithm modeling process,a regular hexagonal antenna array serves as the base structure for forming the transmitting antenna array,with each transmitting antenna treated as a point source.Beams from these sources form planar wavefronts on the receiving surface.Calculation of the beam angle between the beam of each antenna and the normal of its aperture enables deduction of the field strength direction at the receiving points.Moreover,the field strength vector is decomposed along three coordinate axes,considering phase shift in the wave propagation of the antenna field strength,to facilitate power combining using the wave equation.Finally,simulation validates the effectiveness of the spatial power combining algorithm,providing an innovative method for research in this area.
