| Abstract: | With the development of light and small Unmanned Aerial Vehicles (UAV), the detection method of Mini SAR based on UAV platform brings a revolutionary impact on information acquisition mode. In this paper, a W-band Mini SAR system for UAV is proposed, including the system design proposal and composition, high linearity analog phase-locked frequency modulation, MilliMeter Wave (MMW) substrate integrated waveguide antenna, 3D integration and motion compensation methods to solve the key problems of Mini SAR. A W-band Mini SAR prototype is developed and the imaging test based on Multi-rotor UAV is proceeded. The results show that the resolution, volume and the weight of Mini SAR prototype is at the industry-leading level. A high SNR imaging with perfect focusing effect is obtained from flight test. |
