Background:
The growing request of better performance and the increase of the number of radar applications and, consequently, number of radars already in place, call for wider and wider bandwidths, which ultimately generates a conflict with the bandwidth demand from communication systems, requiring novel techniques for co-existence between radar-based sensing and communication technologies, in the form of cooperative or non-cooperative operations. In this framework, a number of possible architectures can be devised, ranging from the mere coexistence of nearly independent systems, possibly negotiating the physical resources to be shared, to fully integrated systems, wherein coexistence is purely functional and energy efficiency is a major constraint. Communications and radar systems can be also co-designed for mutual benefit.
There is also ongoing broad technology convergence in the areas of wireless communications systems and fully adaptive multifunction radars. Such convergence takes place, for example, in Radio Frequency circuit design, in the use of large aperture multiantenna systems, multifunction hardware, fully adaptive transmitters and receivers capable of launching and processing many waveforms and tasks simultaneously,
While this integration is foreseen as the standard for future 6G networks (IoT, smart cities, smart transportation, autonomous vehicles, etc), in particular in mmWave regime, the impact and perspectives of this new paradigm on classical radar applications has not been fully explored and analyzed.
Objectives:
The objective of the ET is to perform theoretical investigations to assess benefits and drawbacks of integration of sensing and communications capabilities in modern radar systems. Specifically, the group will focus on the definition of the scenarios in which the coexistence is unavoidable and the integration is a better choice in terms of energy consumption and performance bounds. The group aims to generate scientific output in the form of publications, conference special sessions and journal special issues.
Topics:
The group will focus on the following topics:
• Interference avoidance strategies in non-cooperative radars and communications systems
• Exploitation of interference from cooperative sensing and communications systems earlier considered as nuisance to be mitigated.
• Optimized, possible cognitive, resource allocation and sensing/communication waveform design in partially cooperative and fully integrated systems.
• Exploitation and countermeasures for the new sensing, localization and tracking functionalities integrated in future networks (e.g. 6G).
These topics will be investigated for the specific radar applications of interest to the participants.
