The figure above shows the RD map generated from the fast chirp signal processing in subframe 1. The RD map from the slow chirp signal processing in subframe 2 is not shown because it is the same as that of subframe 1, but this is actually incorrect — the correct situation should be that the Doppler index positions of the two subframes are different. In addition, the stepped frequency has been configured within the maximum hopping range of 450 MHz as you previously corrected. Within each subframe, each chirp has a fixed frequency hop of 1.1 MHz, hopping 384 times, so the carrier frequency of the last chirp is f = 76 GHz + 383 × 1.1 MHz. However, the clutter slope shown in the signal processing does not properly reflect the stepped frequency relationship. The stepped frequency amount derived backward differs significantly from our preset value. We also conducted experiments using corner reflectors, but the discrepancy still exists. Therefore, could you please help us identify whether the issue lies in the configuration mentioned above, or if there are other reasons or limitations? Please point out the root cause for us.
