摘要大到银行等企业的安保工作,小到汽车的道路安全问题,都需要用到场面监 视,摄像头、红外探测等进行场面监视的辅助设施,在遇到短暂停电、雨雪大雾 天气时受到较大限制,采用场面监视雷达能够有效避免这些环境因素的影响。目 前国内外对于场面监视雷达的研究主要集中在高成本、中远程的领域,因此对于 低成本、小体积却能满足人类日常需求的场面监视雷达的研究有着重要的意义。75285

Title The Design and Implentation of LFM radar signal processing based on FPGA
Abstract Not only the security of banks and other companies, but also the road safety of cars all require the use of field surveillance, cameras, infrared detection and other auxiliary facilities were monitoring the scene, in the face of short-term power outages by comparing the time of rain and snow fog big limitation imposed on the scene surveillance radar can effectively avoid the influence of these environmental factors。 Research is currently for surface surveillance radar research at home and abroad mainly in the field of high-cost, long-range, so for low-cost, small size able to meet the daily needs of the human scene surveillance radar has an important significance。
In this paper, FPGA-based signal processing of LFM radar。 First, the completion of LFM radar range, speed of algorithm analysis, development of the overall system plan; secondly, use Vivado software, each module of the system design, including the realization ranging matched filter design, implementation, speed of MTD design; and finally, simulation debug and validation of each module, complete functional test of the system。
Keywords LFM radar FPGA matched filtering MTD
