Scope and Topics of the Workshop

For the sake of enhancing the exploitation of the permanently allocated, but potentially under-utilized spectral resources, sharing the frequency bands between radar and communication systems has attracted substantial attention. Below 10 GHz, a large portion of spectral resources are primarily allocated to the radar systems, which have seen increasing cohabitation with wireless communication systems, e.g. 5G NR, LTE and Wi-Fi. At the higher frequencies such as the mmWave band, the communication and radar platforms are also expected to achieve harmonic coexistence or even beneficial cooperation in the forthcoming 5G network and beyond. Nevertheless, with the allocation of the available frequency bands to the above wireless technologies, the interference in the radar bands is on the rise, and has raised concerns both from governmental and military organizations for the safeguarding of critical radar operations. To this end, research efforts are well underway to address the issue of communication and radar spectrum sharing (CRSS).

  In general, there are two main research directions in CRSS: 1) Radar-communication coexistence (RCC) and 2) Dual-functional Radar-Communication (DFRC) system design. By considering the coexistence of individual radar and communication systems, the first category of research aims for developing efficient interference management techniques, so that the two systems can operate without unduly interfering with each other. On the other hand, DFRC techniques focus on designing joint systems that can simultaneously perform wireless communication and remote sensing. Doing so enables a paradigm change, where previously competing transmissions can be jointly optimized. This benefits both sensing and signaling operations, decongests the RF environment, and allows a single hardware platform for both functionalities. It is worth pointing out that, these explorations have gone far beyond of their original motivation of realizing spectrum sharing between radar and communication systems, and have been extended to numerous novel applications including vehicular network, indoor positioning and secrecy communications.

  This workshop aims at bringing together academic and industrial researchers in an effort to identify and discuss the major technical challenges, recent breakthroughs, and new applications related to CRSS. Topics of interest include but are not limited to:

  • Spectrum analysis and management of radar and communication systems
