title = "The Phase Error Analysis and Compensation of Mruav-Sar",
abstract = "The multi-Rotor UAV SAR (MRUAV-SAR) platform has a very low flight altitude and poor stability performance, and its trajectory is easily affected by airflow. The low velocity of the carrier platform makes the effect of phase errors greater. This paper first models the phase error of MRUAV-SAR and analyzes the impact of the phase error on the imaging results. Then introduced an estimation and compensation method based on the quadratic phase error and the cubic phase error. Phase gradient autofocus algorithm (PGA) is used to compensate for higher-order phases. Finally, the point target was used for simulation verification, and the results of processing the measured data were compared and analyzed.",
