摘　　要：本文研究了毫米波宽带线性扫频技术，提出了将锁相技术和延迟线结合起来改善线性度这一新思想，并导出了锁相扫频环路的设计准则，采用了无色散的体声波延迟线、数字锁相环路、单片微波器件、高性能的毫米波器件等，结构上采用了高密度组装、ＳＭＴ等先进技术，研制的扫频源主要指标为带宽５００ＭＨｚ，线性度优于０．０１％。In this paper,the millimeter wave wide-bandwidth ultra-linear sweeping technique is studied,the new theory consisting of phase-locked technique and delay-line to improve the linearity is presented,the design principle of phase-locked sweeping loop(PLSL) is deduced,and the non-dispersion delay line, digital phase-locked loop,monolithic microwave components and high-performance millimeter-wave components are used.In structure,the high-density assembly technique and SMT are utilized.The sweeping source's main performance indexes are as follows:Bandwidth is 500MHz,linearity is superior to 0.01 %.
