Abstract
This paper presents a passive position method based on Synthetic Aperture Radar (SAR). By incorporating the SAR imaging technique, the position of the signal emitter is directly determined. The key to this method lies in the range and azimuth compression techniques used in signal processing. To address the issue of range walk for large slant angles, a secondary range compression (SRC) approach is proposed. Simulation results validate the effectiveness of the proposed method.
