The method is based on property of most man-made objects which consist in straight edges and mostly right angles. The developed 2D adaptive image filter assists to detect straight edges even if given image fragment has a low contrast and has been extremely noised, in addition, if an object edge has been distorted, for example, by interference in the SAR azimuth channel, the filter compensates for distortions which do not exceed the specified value. The next processing of line-segment list without image raster works faster and allows detecting a relatively small set of possible targets. This approach could be used as addition for neural networks as well as provide assistance in preparing of training data set.","PeriodicalId":321624,"journal":{"name":"2017 XI International Conference on Antenna Theory and Techniques (ICATT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115793586","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}

All these features are hard to achieve simultaneously. Therefore, for the sake of satisfying these demands, it has been suggested in this study to add parasitic slots to the printed Quasi-Yagi antenna, where by modifying their shapes, sizes and positions within the antenna, a significant performance is obviously detected. Simulation results using CST software suite have shown a clear enhancement in the bandwidth (6:1), and radiation efficiency (Gain = 5dB on average) with a very compact antenna structure allowing it to compete with the well-known antenna systems provided by international antenna companies like KATHREIN and TAOGLASS etc. Results are based on CST simulations and practical measurements.","PeriodicalId":321624,"journal":{"name":"2017 XI International Conference on Antenna Theory and Techniques (ICATT)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129569082","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 proposed method of connection is illustrated by an example of microstrip filter, which is tunable within the frequency range 18–20 GHz. The minimum capacitance of the ferroelectric capacitor, that was obtained, was Cmin = 0.22 pF, the maximum value — Cmax = 0.31 pF. In traditional connection scheme, capacitance value is Cmin = 0.11 pF, and it is not possible to implement ferroelectric capacitors in this case.
