In addition, the terahertz (THz) ISAR is effective in realizing high-resolution imaging on both range and azimuth dimensions for its large bandwidth and short wavelength. However, in the real THz-ISAR imaging scene, the sub-harmonics easily occur because of the components ageing or the defects of the device-processing technology. The sub-harmonics embodied in both amplitude and phase terms lead to the deterioration of ISAR imaging quality. This paper analyses the property of the sub-harmonics appeared in the 330GHz ISAR imaging experiment and proposes a threefold correction method by reference signals of two reflectors to suppress the sub-harmonics.","PeriodicalId":326539,"journal":{"name":"2018 11th UK-Europe-China Workshop on Millimeter Waves and Terahertz Technologies (UCMMT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130968915","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 near-field characteristics based on the square, circular and regular triangular topologies are calculated accurately. The correctness of the calculation is verified by the simulation. It is found that the circular sparse array has the best performance in sparsity and focusing ability among three topologies. Then, the influence of the regular change in the element distance of the circular sparse array is discussed. The best selection criterion for the near-field focusing sparse array antenna is that the distance between two elements on the ring and the distance between two rings are two constants.","PeriodicalId":326539,"journal":{"name":"2018 11th UK-Europe-China Workshop on Millimeter Waves and Terahertz Technologies (UCMMT)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123934950","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}

We take two surfaces amplitude-only data at space domain using angular spectrum propagation theory to iterates between two parallel surfaces. $varphi=0^{circ}$ and $varphi=90^{circ}$ at the first surface is chose to show the fitting degree between the simulated phase from GRASP and the phase retrieved from matlab.
