To solve the problem, this paper designs an inter-segment parallel algorithm based on the extended cancellation algorithm batches (ECA-B) of LDLT decomposition. Firstly, based on the GPU multi-thread parallel processing technology, the effectiveness of the ECA-B algorithm is improved by segmented parallel processing, which is combined with the same sub-module characteristics of each segment of the ECA-B algorithm. Then, the cost of the time of data transmission in the inversion process of traditional ECA-B algorithm is economized by proposing a parallel iterative inversion method based on LDLT leveraging the conjugate symmetry property of covariance matrix, which is processed by two CUDA kernel function and further improves the execution efficiency of the parallel algorithm between segments. Experimental results show that the algorithm performs higher effectiveness compared with the traditional algorithms.","PeriodicalId":179327,"journal":{"name":"2022 IEEE 5th International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128797610","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 proposed method improves the target-to-clutter ratio (TCR) by combining the relative differences of multi-features between ship target and the clutter background, and the threshold segmentation is performed based on the final local enhancement results. The experimental results show that the proposed method can suppress clutter background and speckle noises, improve the TCR and the algorithm has a high detection rate and a low false alarm rate in the complex background and multi-target marine environment.","PeriodicalId":179327,"journal":{"name":"2022 IEEE 5th International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126676426","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 horizontal polarization (HP) element is designed as the metal ground of the vertical polarization (VP) element to avoid match deterioration when the HP element is positioned closely to the metal ground of the VP element. Thus, the dual-polarized antenna realizes an extremely low profile of 0.07 λmin (λmin is the wavelength at the minimum frequency in the operational band). The designed antenna achieves an overlapping bandwidth of 1.7-8 GHz (130%) and an isolation higher than 20dB within the band.
