  • Airborne forward-looking SAR based on array technology can supply high-resolution images of the area with respect to forward direction of the flight path. However, micro-motion of the array antenna may affect imaging. Extraction method of micro-motion characteristic parameters based on time-frequency analysis is proposed, and influence of array antenna micro-motion on forward-looking SAR imaging and the compensation method are investigated. Firstly, micro-motion model of array antenna is established based on antenna characteristic of forward-looking SAR, and compensation method of array antenna deformation is analyzed. Then, time-frequency characteristic of array antenna micro-motion is studied based on time-frequency analysis method. Finally, imaging simulation of point target in the condition of antenna micro-motion is done. Imaging results before and after compensation are compared combined with imaging characteristic. Results indicate that the established model and proposed method are correct and valid.
