Bio and Abstract

Abstract

Illicit use of drones poses a critical threat, necessitating robust systems for drone detection and classification. Radar offers all-weather, day/night capability for drone sensing at a distance. However, generating comprehensive radar drone datasets via field measurements is prohibitively expensive and constrained. To address this, we have demonstrated the potential use of full-wave electromagnetic computer-aided design (EM CAD) tools to create radar-drone digital twins. This approach enables the synthesis of multi-parameter drone and radar models to generate tailored datasets for advancing drone classification research. We have modeled diverse radar systems (X/Ku/Ka-band) and drone types, including a COTS quadcopter carrying an explosive payload. The digital twins have empowered critical innovations. First, we have showcased that novel artificial intelligence methods can leverage the physicsbased radar signatures and achieve over 90% classification accuracy, even amidst avian clutter. Second, our approach enables examination of radars spanning disparate bands to uncover operating regimes ideal for classification. Third, the flexibility of the digital twins allows us to systematically vary radar/target parameters and generate the diversity and volume of data needed to train deep neural networks empowering unprecedented classification capabilities.
