Improved ENLCS imaging Algorithm for Air-borne Forward-looking SAR

摘要：

Based on problem which side-looking SAR cant image in flight direction with azimuth resolution, an linearity array antenna forward-looking SAR system is studied. According to the spatial geometry and the model of echo signal, extended nonlinear chirp scaling algorithm is proposed for forward-looking SAR. The phase compensation factors and realized steps of algorithm are given. The mage is achieved by using the ENLCS algorithm proposed in this paper. The imaging effect is analyzed, and the Simulation results demonstrate the validity of the algorithm.
