The frequency spectrum is becoming increasingly more congested and contested due to rapidly increasing bandwidth of radar sensing and communication systems. The integrated sensing and communication (ISAC) systems that utilize the same frequency resources for both operations are seen as key solutions for the congested frequency spectrum problem.
ISAC systems can be designed as radar-centric or communication-centric systems based on the waveforms that are utilized. In the radar-centric ISAC systems, the communication data is embedded in radar signals, while communication-centric ISAC solutions exploit the communication signals for radar sensing.
