N2 - Aimed at the shortage of image analog transmission and the requirements of real-time reliable transmission for micro unmanned air vehicle, a digital image wireless transmission scheme is proposed, adopting the improved set partitioning embedded block coder(SPECK) compression algorithm based on 5/3 lifting wavelet; with the channel error correction coding based on Turbo code and spread spectrum. On the base of representing this scheme, the key technologies and countermeasures are discussed. Experimental results showed that this scheme possessed many characteristics, such as high compressibility, fast operating speed, good real-time, strong ability of resisting error etc, and is applicable for the specific needs of micro unmanned air vehicle.
