Ship Velocity Estimation in Airborne Along-Track Interferometric SAR Imagery Based on the Fractional Fourier Transform

Figure 7

Estimation results as a function of range acceleration varying from 0.01 m/s2 to 0.1 m/s2 at  = 4 m/s and  = 4 m/s. (a) Absolute error in the azimuth velocity estimation using the proposed method, (b) a comparison of the errors from the proposed method and contrast method, (c) absolute error in the range velocity estimation using the proposed method, and (d) absolute error in the range acceleration estimation using the proposed method.
