摘要

本文首先从理论上分析了传统的线性调频连续波(FMCW)雷达在进行多目标识别中的局限性

提出了一种采用变周期的线性调频波形作为发射波形的新方法

从而解决了多目标识别中的虚假目标的问题.计算机模拟证明了理论分析的正确性和新方法的可行性.最后

针对这种体制雷达探测系统的新特点

提出了一种适用于该系统的容差函数.

Abstract

The traditional FMCW(frequency modulation continuous wave) radar has its own limitation in multitarget detection.In this paper a novel method by using changing cycle FMCW radar is presented.Computer simulation proves that the analysis is correct and the method is practical.Considering the different frequency resolution rate of velocity in different periods

a special function is given to decide the error range of one target.
