This technology can be widely used in automatic driving, medical imaging, disaster rescue, and military anti-terrorism. In the paper, We propose a millimeter-wave (MMW) NLOS imaging system, which is less expensive, more robust and harder to be detected. Based on the specular scattering property of MMW and synthetic aperture radar (SAR) technique, we demonstrate the feasiblity of MMW NLOS by experiments.","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":"122825423","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}

Single-layer multi-polarization transmission multi-functional metasurface (MTS) is designed by using the developed unit. Orbital angular momentum (OAM) mode and pattern reconfiguration is achieved by switching left hand circular polarization (LHCP) or right hand circular polarization (RHCP) horns. Then, the desired OAM mode, beam direction and beam polarization can be generated arbitrarily by tailoring the size and rotation angle of the MTS element. Finally, the MTS with LHCP incidence or RHCP wave incidence are simulated, the results validate the design principle, which shows a great flexibility for designing multi-beams multi-polarization multi- functional MTS-based devices. Moreover, the proposed MTS has low profile, arbitrary polarizations, beam numbers and modes, and can be reconfigurable.","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":"122074256","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}

The estimation under the mutual coupling condition generally involves the joint estimation of the mutual coupling matrix of the array and the arrival direction of the signal, which has the disadvantages of difficult search of the two-dimensional spectral peaks and large computational effort. In this paper, an estimation algorithm based on a shaped array is proposed without the need for mutual coupling matrix estimation. The estimation of the signal is accomplished by reasonably selecting two subarrays that are rotationally invariant under the influence of mutual coupling.","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":"117068240","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}
