This study introduces the design and evaluates the performance of Joint Radar and Communication (RadComm) system, aimed at maximizing spectral efficiency by integrating radar sensing and wireless communications into a single framework. The development of this system is motivated by the increasing demand for electromagnetic spectrum resources, necessitated by the expansion of wireless communication networks and the need for sophisticated radar technologies. Our RadComm system proposes an innovative waveform that supports high-resolution radar sensing alongside reliable communication functionalities, adapting dynamically to various operational conditions. Performance metrics, including radar detection accuracy, communication throughput, and BER, are thoroughly analyzed under diverse environmental challenges such as interference, mobility, and multipath fading. The study also explores signal processing strategies for enhancing the system's robustness against spectral congestion. Results indicate that the RadComm system not only achieves efficient spectrum use but also maintains high performance in both radar and communication domains, showcasing its potential for future dual-purpose applications such as autonomous navigation systems and next-generation wireless infrastructure. This research underscores the feasibility and advantages of RadComm systems in achieving efficient and flexible use of the electromagnetic spectrum.
