Analysis of a Chirp-Based Waveform for Joint Communications and Radar Sensing (JC&S) using Non-Linear Components

Joint communications and radar sensing (JC&S) is expected to be one of the key features in beyond 5G (B5G) networks, allowing the provision of radar as a service (RaaS). In this paper, we are interested in a chirp-based waveform that can be effectively employed for both communication and radar applications. More specifically, we investigate the performance of such a waveform in the presence of realistic non-linear power amplifiers (PA) and low-noise amplifiers (LNA), operating at mmWave frequencies.
