Abstract

A 2-D ESPRIT type method is presented for the scattering centers measurements in step-frequency radar. This method estimates the signal parameter pairs directly unlike the matrix enhancement and matrix pencil (MEMP) method which contains an additional step to pair the parameters related to each dimension. We use a forward-backward prediction data matrix to increase the estimation accuracy and the robustness to noise. Results compared with the Fourier transform method show that the resolution and precision of the 2-D ESPRIT type method are both higher than those of the Fourier method.
