Abstract

Aiming at the problem of edge point defocusing of arbitrary configuration bistatic SAR based on traditional Taylor series expansion slant range method, this paper developed a 2D frequency domain imaging algorithm based on Legendre orthogonal polynomial approximation. This algorithm derived the 2D spectrum of the point target based on the Legendre polynomial expansion of the slant range function, which eliminated the coupling of range and azimuth of the echo signal and made the imaging processing more efficient. 2D frequency domain imaging algorithm imaged the point target of scene region in 2D frequency domain. The algorithm improved the focusing effect of scene edge points and increased the focusing depth of scene edge points. The theoretical derivation and simulation results verify the effectiveness and feasibility of the proposed algorithm.
