Abstract
In this chapter, delay-Doppler information acquisition in the RIS-enabled ISAC system is studied. In Sect. 4.1, the introduction is first provided. In Sect. 4.2, we introduce the system model of the RIS-enabled OFDM ISAC system. Section 4.3 presents the coarse-grained sensing via Delay-Doppler estimation, while Sect. 4.4 introduces the fine-grained sensing via Delay-Doppler estimation. Numerical results and discussions are provided in Sect. 4.5. Finally, Sect. 4.6 summarizes this chapter.

Notes
- 1.
In our considered system, the bandwidth is much smaller than the carrier frequency (i.e., \(B\ll f_c\)) and the wavelength is approximately constant over the entire bandwidth.
- 2.
We consider the full-duplex BS that the transmitting and receiving antennas work simultaneously without self-interference.
