Table 3: RMSE values of the estimated radial velocity relative to data generated with different values of SCR using the target deterministic RCS model processed with Gaussian RCS-derived likelihood functions, using, respectively, the nominal value of SCR ( S C R 𝑒 ) , the estimated (by (9)) value of SCR ( S C R 𝑓 ) , and a fixed value of SCR = 30 dB 𝛾 𝑐 = 1 . All other parameters (CNR = 10 dB, 𝑢 𝑟 , etc.) are fixed.
