Therefore the use of simulated data is inevitable for convergence of deep models (DMs). However generating synthetic data for real-life complex targets can be quite tedious and is not always possible. In this study DMs trained with synthetic one-dimensional scattered data of elementary targets are transferred to classify complex targets from measured signals for the first time. For this purpose a novel system is proposed by combining three strategies: first initial training of DMs using analytical and simulated time domain scattered data obtained from the basic targets, second the last layers of initial DMs are fine-tuned by transfer learning using measured signals of the real targets, and third an ensemble model is developed to generate a model that can completely represent real target characteristics by combining diverse and complementary properties of the fine-tuned DMs. The proposed system provides higher accuracy sensitivity and specificity performances compared to the existing methods.EnglishDeep learning (DL), ensembles, target classification, time-domain scattered signals, transfer learning (TL)ROBUST CLASSIFICATION, RECOGNITION, NETWORKS, WAVEArticle
