摘要:Multi-rotor LA V is a popular platform for low-cost SAR system because it has small volume, lightweight and flexible motion. However, due to complicated flight trajectory and low-accuracy motion sensor, autofocus in SAR processing becomes a challenging problem. In consideration of the characteristics of multi-rotor LTA V SAR, this paper proposes an autofocus algorithm based on improved Mapdrift technology. The proposed algorithm can estimate the realtime velocity of multi-rotor 1.1,4V SAR and compensate the motion error, and then process the signals with range-Doppler algorithm.
