Based upon the fact that different signals result in different AF structures, the proposed method selects the rotation angle and cloud model similarity coefficients of AF main ridge slice as feature parameters, and constructs the feature vectors for the classification and recognition of radar emitter signals. In the process of feature extraction, Empirical Mode Decomposition (EMD) is employed to weaken the influence of noise on main ridge slice envelope. In simulations, Kernel Fuzzy C-means (KFC) clustering is adopted to realize the recognition of different types of radar signals. Experimental results show that aggregation within class (AWC) and separability between classes (SBC) of extracted feature vector remain good in spite of dynamic SNR. The proposed method is capable of classifying and identifying radar emitter signals with higher correct recognition rate (CRR) in comparison with existing methods.","PeriodicalId":423697,"journal":{"name":"2016 8th International Conference on Ultrawideband and Ultrashort Impulse Signals (UWBUSIS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121092225","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}

Although the new methods of cancer treatment are very effective, successful treatment is possible only with diagnosing the early stages of the disease. Therefore, creating new and harmless methods for early or pre-clinical diagnosis of cancer is an important task at present. The report describes the main issues and challenges related to development of microwave imaging systems of biological objects. The original hardware-software system for the study of biological objects was created. The system operates in the frequency range of 137.5 - 4400 MHz and has a sensitivity of 55 dB. The study and visualization of investigated object is performed according to the measurement scattering in the near field region. Solutions of salts and glucose were used as phantoms of biological objects. The fundamental possibility of detection and visualization of contrast areas of the internal environment as the gradients of the permittivity and conductivity is shown.","PeriodicalId":423697,"journal":{"name":"2016 8th International Conference on Ultrawideband and Ultrashort Impulse Signals (UWBUSIS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117228279","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}
