- Abstract
- Joint radar and communication systems are promising technologies, envisioned for numerous future applications, e.g. vehicle-to-everything networks, smart home, environmental monitoring, or smart manufacturing and industrial internet-of-things. On the one hand, the radar or sensing function aims to gather information about the unknown environment. On the other hand, the communication function objective is to transmit information between devices, in a supposedly known environment. In recent years, the possibility to operate both functions simultaneously has received an increased attention, but it has also raised multiple challenges. In this PhD thesis, the sensing and communication have been analysed under multiple facets. Vehicular scenarios have for instance been considered, starting from the electromagnetic modelling of radar and communication links to the evaluation of the performance achieved at the scale of a complete city. First, at the vehicle level, novel electromagnetic-based signal models have been developed. Then, at the street level, the interference between the two functions have been studied, when two nodes equipped with joint radar and communication systems are operating simultaneously. Two different mitigation techniques have been proposed. Finally, at the city level, complex interference models have been developed, and the average performance of typical systems has been evaluated.
