Performance Analysis of Resolving Left/Right Ambiguity in Multichannel Forward-Looking SAR Imaging

Radar forward-looking imaging is important in many fields, such as the ground mapping, autonomous driving. However, conventional monostatic SAR cannot realize forward-looking imaging due to left/right ambiguity. In this paper, based on the geometry model of multichannel forward-looking SAR, the principle of resolving left/right ambiguity is illustrated firstly, and then the performance is analyzed. At last, simulation results are illustrated to verify the effectiveness of theoretical analysis.
