Multichannel Along-Track Interferometric SAR Systems: Moving Targets Detection and Velocity Estimation

Figure 14

CRLB^1/2 (solid line) and RMSE (dashed line) values (in log scale) of the estimated target radial normalized velocity, with CNR = 10 dB, SCR=0,10,20dB, 𝛾_𝑐=1, for a single-baseline system (𝑏₁=1.2m) for (a) a deterministic modeled moving target and (b) a Gaussian modeled moving target.
