| contents | Joint radar-communications (JRC) technology has attracted massive attention for decades, since it can effectively utilize allocated spectral resources by sharing frequency bands in increasingly crowded environments. In addition, the growing demand for hardware platform sharing which benefits both functionalities motivates more cooperation between radar and communication systems. In order to achieve the coexistence of sensing and communicating operations, joint systems should be designed to perform both tasks simultaneously. Developing a joint radar-communications waveform which is suitable for both functions is extremely crucial for this type of co-design, as it not only decreases spectral impact, but also benefits performances of both systems mutually. In this paper, a joint radar-communications waveform is utilized to perform GEO SA-Bi SAR imaging and wireless communication simultaneously. We also design a joint radar-communications receiver in this context to demonstrate feasibility of achieving both sensing and signaling with GEO SA-Bi SAR system. |
