초록

드론 기술의 급속한 발전과 다양한 산업에서의 응용이 크게 확대되어감과 함께 보안 위협 또한 증가하고 있으며, 이를 해결하기 위한 연구가 요구되고 있다. 본 연구에서는 드론 분류를 위하여 RF 신호를 사용하였고, 이를 전처리하기 위해 웨이블릿 변환, STFT 및 Mel-Spectrogram 분석을 수행하고, 이를 이미지로 변환하여 학습하는 CNN 기반 학습 모델을 개발하였다. 또한 Image 변환 과정에서 병렬 처리를 최적화하여 계산 속도를 향상시켰다. 제안된 모델은 기존 Spectrogram 변환 방식 대비 학습 속도를 크게 단축하며, 실시간 탐지에 적합한 성능을 보였다. 결론적으로, 본 연구는 Image 변환 방식을 통한 CNN 모델을 통해 RF 신호 기반 드론 탐지의 분류의 정확성과 실시간성을 향상시켰다.

Abstract

The rapid advancement of drone technology has led to increasing security threats, requiring effective countermeasures. This study presents a CNN-based model for drone classification using RF signals, processed with wavelet transform, STFT, and Mel-spectrogram. By optimizing parallel image conversion, the model achieves faster computation and supports real-time detection. The proposed approach enhances both classification accuracy and real-time performance compared to conventional methods.
