该文提出了一种快速、通用的射频仿真近场效应修正算法.利用重心公式以及待求的真实目标点方位所对应的三元组馈电系数表达出一个虚拟方位点.在近场修正中,利用虚拟方位点的收敛逼近来代替真实目标点的收敛逼近,而虚拟方位点的收敛逼近使用差分重心公式.基于差分重心公式的算法可以很快地实现收敛.与传统方法相比,该算法迭代公式非常简单,并且与后续雷达信号处理无关,具有更广的适用性.通过数值仿真,验证了分析结果.该算法对于射频仿真近场修正具有重要意义.
This paper presents a fast algorithm of the near-field-error correction in radio frequency simulation system.A simulated direction can be expressed based on the mass center formula and the feed parameters of three-unit.The iterative convergence for the real direction of the target can be replaced by the convergence for the simulated direction
and the latter can be calculated by the differential formula of the mass center.The algorithm based on the differential formula of the mass center can converge quickly.Compared with the traditional method
the used iteration formulas are simpler and feasible for various kinds of radar systems.The conclusions are verified by the numerical simulation.
