A multi-target signal generator provides to the MSPG-MT with multi-target signals generated by multiple direct-digital synthesizers (DDSs). The MSPG-MT provides to antennas with individual multiple scattering points of the multi-target generated by multiple divider blocks. The HRR receives the radiated signals from antennas and displays the multiple scattering points in the beat frequency domain. The validation of the proposed MSPG-MT was verified through a measurement using a Ku-band HRR and the MSPG-MT.","PeriodicalId":383603,"journal":{"name":"2019 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125242504","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}

For raster-scanned focused spot antenna systems, both the focusing array antenna and the target region must be finely and fully sampled, but the intervening space is large, making the computational space huge. For focusing along the axis in target geometries with only material variation in range, it is possible to scale the transmitter/receiver array and its range to target by a factor of two or four. But for even small amounts of off-axis focusing, the scaling must be done with care to avoid specular reflected rays that might miss the scaled transceiver array. Simulations based on ray analysis, analytic arrays of dipoles, and Quasi-Axisymmetric Finite Difference Frequency Domain (QAFDFD) compare well with each other. Only QAFDFD, however, can model target edge effects in the presence of large ground planes.","PeriodicalId":383603,"journal":{"name":"2019 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125273243","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}

Intelligent anti-jamming decision for multi-domain, which is more flexible than traditional single-domain technique, has attracted much more attention. However, poor decision-making speed and robustness of decision-making algorithm lead to a non-optimal communication scheme in huge decision space. An anti-jamming decision method based on the mutation search artificial bee colony algorithm (MSABC) is proposed in this paper. Numerical investigations show that the proposed algorithm can find a better communication scheme that reduces the normalized transmitting power while maintaining the normalized rate.","PeriodicalId":383603,"journal":{"name":"2019 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125387150","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}

A convolutional neural network consisting in two convolutional layers and two fully connected layers is constructed as the recognition classifier with less dependence of feature extraction. The network is trained with 1000 groups of datasets and verified by testing recognized results as the customized shortcut keys.
