There is a lower boundary for the synthesized beamwidth with a fixed array scale, and the aperture efficiency is inversely proportional to the desired beamwidth as well. Thus, for millimeter-wave applications, a trade-off design should be considered between the desired beamwidth and the aperture efficiency with a fixed antenna array.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124294236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the parameters of the received paths are resolved using channel state information (CSI) and then the desired paths are extracted using the K-means clustering algorithm combined with the prior information of the reflector. Secondly, the relative time of flight (rTOF) is used to establish the localization model, and the rough estimation of target location is obtained from semi-definite programming (SDP). Then the least squares (LS) is used to solve the target location. Finally, we implement the proposed system in the real indoor environment, and the experimental result shows that the proposed system can achieve a localization accuracy of 1.3 m in the NLOS environment.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129469477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a LFMCW radar target detection system based on Zynq platform is designed and implemented, which has high integration, low cost and small size. The system makes full use of the advantages of Zynq-7000 platform, uses the Processing System(PS) part of Zynq-7000 to flip the data of range dimension Fast Fourier Transform(FFT), and transfers the flipped data to Progarmmable Logic (PL) part through Direct Memory Access (DMA) to realize Moving Target Detection (MTD) and Order Statistic Constant False Alarm Rate(OS-CFAR). MTD is implemented by slow time dimension FFT, while the implementation of OS-CFAR needs to consider the characteristics of PL parallel execution, that is, the thinking mode of parallel sorting is used in the sorting steps of OS-CFAR, and the area is used to exchange less processing time to ensure the real-time performance of the whole system.","PeriodicalId":197691,"journal":{"name":"2022 IEEE 10th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128387016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
