摘要

根据ＦＭＣＷ雷达的工作原理，本文采用新技术和小型化３ｍｍ元部件，设计了先进的３ｍｍ前端电路，大大减小了组件体积，并采用了模拟一数字混合电路，由高速单片计算机完成了对３ｍｍＶＣＯ的调频线性度闭环实时校正．组件工作频率９４．８ＧＨｚ，调频带宽２８０ＭＨｚ，发射功率大于５ｍＷ，调频线性度优于０．２‰．

Abstract

On the basis of the principle of FMCW radar

this paper applies new technology and miniature unit circuits at W-band

proposes an advanced front end at W-band. Volume of the front end is decreased greatly. Analog-data hybrid circuits are used. A high speed chip computer is applied to complete FM linearity closed-loop real-time calibration for VCO at W-band. Operatingfrequency of front ends is 94. SGHz

FM bandwidth 280MHz

FM linearity below 0. 2%

transmitting POwer more than 5mW.
