عنوان فارسی Novel Use of PRF Sound for Radar Emitter Recognition: A Transfer Learning-Infused DCNN Study
چکیده فارسی مقاله In contemporary electronic warfare, the accurate and prompt identification of radar emitters is crucial, especially for the efficiency of electronic countermeasures. This study presents a new method that utilizes pulse repetition frequency (PRF) sound to identify radar emissions in response to the growing intricacy of modern radar systems. This study employs six transfer learning-based deep convolutional neural networks (DCNNs) to extract features. It provides a comprehensive examination of classification performance and computational efficiency across several DCNN designs. The VGG16 and ResNet50V2 models achieved recognition accuracies of 95.38% and 96.92%, respectively, with training times of 8.01 seconds and 21.25 seconds. This study also examines the trade-offs between accuracy and computational requirements, offering a strategic understanding of the subtle dynamics of radar emitter recognition. In situations when computational complexity is not the primary concern, ResNet50V2 is the most suitable choice. Alternatively, VGG16 is recommended due to its ability to compromise high accuracy and lower computing demands. This study establishes a standard for future research endeavors, which encompass enhancing the capabilities of models at a larger scale, optimizing current architectures without sacrificing accuracy, and progressing towards models that can autonomously adapt to hardware limitations. The results provide a thorough manual for choosing DCNN models that can effectively detect six different input types in various computational settings. This paves the way for creating advanced models that strike a harmonic balance between efficiency and accuracy.
