摘要
提出了一种３ｍｍ线性调频源线性度的实时闭环校正方法。应用该方法研制了３ｍｍ线性调频源线性度校正系统。重点对这种实时闭环校正方法进行了计算机模拟研究，证实了３ｍｍ线性调频源稳态线性度高，可满足３ｍｍ线性调频连续波雷达的高线性度要求。
A real time closed loop correction method of linearity for 3mm linear frequency modulated(LFM)source is presented in this paper.Based on this principle,a linearity correction system of 3mm linear FM source and its computer simulation is completed.The high stable lineari-ty of this 3mm linear FM source is detected using above principle,which satisfies the requirements of High linearity of 3mm linear FMCW radar.
