摘　　要：在数字阵列雷达固有相位的工程测定过程中,信号源与雷达阵列之间的位置关系通常存在一定的误差。这种误差可能会导致雷达固有相位测量结果的不准确,从而影响雷达系统的整体性能和数据处理效果。为了应对这一挑战,文章将位置误差因素引入测量模型,提出了一种适应位置误差的相位一致性测定方法。该方法结合了信号处理和误差补偿技术,能够有效地修正因位置偏差导致的相位测定错误。通过理论推导和实测验证,文章证明了该方法在复杂环境下的适用性与有效性。实测结果显示,应用该方法后,雷达固有相位的测量精度显著提高,从而为数字阵列雷达在实际应用中的可靠性提供了重要支持。In the process of engineering measurement of the inherent phase of digital array radar,there is often a certain degree of error in the positional relationship between the signal source and the radar array.This error can lead to inaccuracies in the measurement results of the radar’s inherent phase,thereby affecting the overall performance of the radar system and its data processing capabilities.To address this challenge,this paper introduces the positional error factor into the measurement model and proposes a phase consistency measurement method that adapts to positional errors.This method combines signal processing and error compensation techniques,effectively correcting phase measurement errors caused by positional deviations.Through theoretical derivation and practical verification,we demonstrate the applicability and effectiveness of this method in complex environments.The experimental results show that the measurement accuracy of the radar’s inherent phase is significantly improved when this method is applied,thereby providing important support for the reliability of digital array radar in practical applications.
