The effect of the phase error introduced by the 1-bit phase correction is studied. An optimization method of the 1-bit discrete phase shift distribution is proposed to reduce the influence of phase shift error on nondiffractive beam. The numerical simulation and measurement results indicate that the 1-bit phase correction reflectarray using the proposed optimization method can effectively generate and steer the quasi-non-diffractive beams. The beam steering speed is up to 40,000 times per second.","PeriodicalId":274385,"journal":{"name":"2020 13th UK-Europe-China Workshop on Millimetre-Waves and Terahertz Technologies (UCMMT)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123133113","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}

One major concern in the small setup is its high reflectivity level, which might distort the quiet zone performance significantly. Meanwhile, it is critical that the quiet zone performance is insusceptible to system inaccuracies. In this paper, a new PWS strategy is proposed based on parametrized field distribution over an enlarged sampling area, which offers robust design and low reflectivity level. The effectiveness and robustness of the proposed PWS strategy is demonstrated in a numerical simulations.","PeriodicalId":274385,"journal":{"name":"2020 13th UK-Europe-China Workshop on Millimetre-Waves and Terahertz Technologies (UCMMT)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117241660","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 order to study the scattering characteristics of clothes made of different materials in the terahertz band, a terahertz radar system operating at 220GHz was used, and experiments on six kinds of clothes were carried out. It can be seen from the results that all kinds of clothes tested cannot completely block the penetration of the terahertz wave. On this basis, super-resolution imaging of the mannequin in clothes is realized through the orthogonal matching pursuit algorithm combined with compressed sensing theory. The results show that this algorithm has better resolution and anti-interference performance than the traditional one-dimensional imaging algorithm.","PeriodicalId":274385,"journal":{"name":"2020 13th UK-Europe-China Workshop on Millimetre-Waves and Terahertz Technologies (UCMMT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128206038","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}
