A light-weight SAR system for multi-rotor UAV platform using LFM quasi-CW waveform

State of the art UAV technology shows its advantage in both civil and military applications, and it is required to meet the needs for payloads special designed for UAVs. However, electric powered multi-rotor UAV provides limited power and more sensitive to the payloads mass. Linear frequency modulated quasi continuous wave SAR leads to small and efficiency radar system which meets multi-rotor UAV's requirements. This paper provides a C-Band UAV SAR combining with linear modulated quasi continuous wave technique as well as integrated radar and communication design. Experiments will be taken to verify the usage of UAV SAR in typical SAR working mode and GMTI ability.
