摘　　要：基于口径场反演的相控阵校准技术,开展探头与待测天线距离误差对校准精度的影响研究。在理论上对引入的误差进行泰勒展开,分析误差项对幅相校准的影响,当略去高阶项时,得到距离误差控制在十分之一波长范围内,可保证其校准精度,并通过仿真设计验证了该理论分析结果的正确性,可为相关相控阵天线诊断和校准提供依据。Based on the phased array calibration technology of aperture field inversion,research is conducted on the impact of probe-to-antenna distance errors on calibration accuracy.The theoretical analysis involves the Taylor expansion of the introduced errors,assessing their effects on amplitude and phase calibration.By neglecting higher-order terms,the distance errors are controlled within a tenth of a wavelength range,thereby guaranteeing calibration accuracy.The correctness of these theoretical findings is verified through the simulation design,validating their applicability as a theoretical basis for phased array antenna diagnosis and calibration.
