Abstract

Abstract:

The scattering center signal model based on geometric diffraction theory (GTD) can accurately describe the electromagnetic scattering characteristics of stealth targets, and the total least squares-estimating signal parameter via rotational invariance technique (TLS-ESPRIT) algorithm is introduced into this model, providing a super-resolution algorithm for the extraction of scattering center. For the problem that the estimation precision of TLS-ESPRIT algorithm under the condition of low signal to noise ratio (SNR) is not high question, introducing the Hankel matrix to improve the TLS-ESPRIT algorithm for echo data processing, the improved algorithm improves the estimation accuracy of scattering center parameters at low SNR, has better noise robustness. It is of great significance in target recognition and radar cross section (RCS) reconstruction.

Key words: total least squares-estimating signal parameter via rotational invariance technique (TLS-ESPRIT) algorithm, Hankel matrix, scattering center, radar cross section (RCS) reconstruction
