Abstract
By taking full advantage of the scattering center distribution in the high frequency regime, this paper proposes a three-dimensional (3D) imaging and micromotion parameter estimation method for cone-shaped targets, which obtains the true 3D scattering center distribution without the need for image scaling and estimates the micromotion parameters simultaneously. Further, it is robust to deal with shadowing effect and low signal-to-noise ratio (SNR). Imaging results of simulated data generated using both the fixed point scattering model and electromagnetic (EM) computation have proved the validity of the proposed method.
