【摘要】 提出了线性调频连续波（ＦＭＣＷ）信号的数字实时闭环高线性度校正与测量的新方法，然后对该方法进行计算机仿真，据此研制了３ｍ雷达ＦＭＣＷ信号的线性度校正与测量系统，对３ｍｍＶＣＯ的实验结果表明，校正后的线性度高达０．０２％。与以往数字开环校正和模拟闭环校正相比，本文方法精度高，实现简单。更多还原

【Abstract】 This paper presents s digital real-time closed-loop high linearity correction and test methodfor linear FMCW signals.Then a computer simulation about this method is made.Based on this 3 mm radarFMCW signal linearity correction and system is deeloped.The experimental result about 3mm VCOproves that the corrected linearity reaches to 0.02%, Compared with traditional digital open-loop methodand analog closed-loop method,this more precise and more simple.更多还原
