A classifying method was developed on the basis of the sources of brain signals defined with the use of the inverse solution. In order to prove the correctness of the classification that was developed, a simple device displaying the result of the classifying signals coming from the brain was designed. This was done in such a way as to carry out thought commands to move the right and left hand. Brain control impulses were processed and classified. Thinking about moving the right and left hand is visualized by lighting respective LEDs: green in the case of imagining right hand movement and red in the case of imagining left hand movement. The experiment carried out confirms the correctness of the classification algorithm that was developed.","PeriodicalId":362184,"journal":{"name":"2018 Baltic URSI Symposium (URSI)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132067400","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}

Defense against an attack performed by an UAV is difficult because its fast speed, maneuverability and small size. Air defense systems with anti-drone capabilities are equipped with a variety of sensors providing efficient detection of UAVs.
