In this paper, a 3-D imaging system is proposed. It works in W-band in order to achieve high resolution.

The experiment results show that the resolution of the image is better than 5mm. This system is described in detail along with imaging results.","PeriodicalId":269888,"journal":{"name":"2015 Asia-Pacific Microwave Conference (APMC)","volume":"459 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121296200","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 output is orthogonalized using Gram-Schmidt method and the envelope of the input signal is characterized by its four and six order moments, named waveform factor Γ and Φ in this paper. Then the gain compression and power of uncorrelated nonlinear distortion are directly expressed using input power Γ and Φ the third-order input intercept point.
