摘　　要：雷达在其发展前期,连续波雷达由于收发隔离等问题不易解决,应用受限制。但是随着技术的发展,这些问题得到改善,连续波雷达越来越受到人们的关注。文章针对现有调频连续波雷达平台,通过分析研究雷达平台,介绍信号处理软件的设计思路与系统结构,设计与开发了信号处理软件。在此基础上,对雷达功能设计实现进行分析,对软件各模式功能进行实验测试,验证了其功能实现及测量精度,并进一步研究调频连续波雷达毫米波雷达用于导弹近程制导的可行性,介绍了调频连续波毫米波雷达的性能,指出其用于末端制导的缺陷并给出改善方法。In the early stage of radar development,continuous wave(CW)radar is not suitable for solving problems such as transmission and reception isolation,so its application is limited.However,these problems have been improved with the development of technology.Thus,CW radar has attracted more and more attention.Based on the existing frequency modulated continuous wave(FMCW)radar platforms,signal processing software was designed and developed by analyzing the radar platform and introducing the design idea and system structure.The paper analyzed the design and implementation of radar function,tested the function of different modes and verified its function realization and measuring accuracy.Further,the feasibility of using FMCW radar was studied in missile short-range guidance,introduces the performance of FMCW radar,points out the defects of its application in terminal guidance and gives improvement methods.
