碩士 === 國立臺北科技大學 === 電子工程系研究所 === 104 === Recently the applications of Unmanned Aerial Vehicle (UAV) enter a prosperity phase, especially for image recording and surveillance, and therefore it is highly needed for developing a UAV-dedicated image transmission system that supports high-speed mobility and Long distances. In this thesis, we develop the image transceiving system with Software Defined Radio (SDR) as well as Raspberry Pi, which can support both high-speed and Long image transmission demands for UAVs and small rockets. The high definition image recorded with Raspberry Pi is transceived by our Digital Video Broadcasting-Terrestrial (DVB-T) transmitter and receiver developed with Universal Software Radio Peripheral (USRP) and GNU Radio. The USRP transmitter equipped with RF power amplifier extends the transmission range, and then the USRP receiver evaluates the signal quality in terms of the Received Signal Strength Indication (RSSI) and Bit Error Rate (BER). We prove that the proposed system provides stable image transmission under the field trial scenarios of moving speed about 50~90 km/h and transmission range about thousands of meters. The use of SDRs for image transmission not only reduces the cost but also has the potential of Multiple Input Multiple Output (MIMO) function supports for better performance in the future.
