In recent years, Integrated Sensing and Communication (ISAC) systems have emerged as a transformative approach for next-generation wireless communication and sensing applications. By merging the traditionally separate domains of sensing (such as radar, sonar, and lidar) and communication, ISAC enables efficient resource sharing and enhanced system performance. A crucial component within ISAC systems is micro-Doppler technology, which captures time-varying Doppler shifts caused by relative motion within a target—such as rotating blades or moving limbs—offering valuable insights for target identification and classification. Micro-Doppler technology leverages electromagnetic sensing to detect frequency shifts induced by fine-scale movements that are often undetectable by conventional Doppler radar. This capability enables distinguishing between different target types through unique micro-Doppler profiles, even in challenging conditions where traditional imaging techniques may fail. The integration of micro-Doppler technology into ISAC systems significantly enhances target detection, identification, and tracking by enabling shared hardware, spectrum, and infrastructure, thus reducing costs and increasing system efficiency. Furthermore, ISAC's simultaneous sensing and communication capabilities improve responsiveness and adaptability, crucial for real-time applications in fields like military surveillance, public safety, and search-and-rescue. This paper examines the synergy between micro-Doppler technology and ISAC, with a focus on signal processing techniques for extracting and analyzing micro-Doppler features, including noise filtering, signal-to-noise ratio enhancement, and target classification. Key challenges, such as real-time processing demands and interference management, are also discussed. Experimental simulations and field trials demonstrate that ISAC-enabled micro-Doppler systems provide robust target discrimination with high accuracy, suggesting substantial potential for applications across various sectors. Future research directions are proposed to further optimize these systems for scalability, reliability, and resilience in diverse operational environments.
