Abstract: A new description of the Synthetic Aperture Radar (SAR) scenario based on the analytical geometrical approach is presented in the paper. The geometry and kinematics of the object and SAR observation system are described in a separate 2-D Cartesian coordinate system. The object space is presented as a 2-D regular grid of isotopic point scatters. The analytical expressions for computing the range distance to point scatters of the object space are derived. The high range resolution complementary phase code image reconstruction procedure is suggested. The image reconstruction procedure includes both range and azimuth compression, accomplished by 2-D Fast Fourier Transform. Range alignment and auto focusing technique to the received SAR signal are applied. The algorithm parameter requirements and limitations are analyzed. The numerical experiments, implemented in MATLAB environment, are presented.

Keywords: Synthetic Aperture Radar (SAR), image reconstruction.
