摘　　要：针对未来实战对短波数据传输的要求,在美军第三代短波网络标准低速数据链路协议(LDL)基础上,提出了将数据分包传输、包长自适应及递增冗余校验等技术应用于短波通信,实现在复杂的短波信道条件下数据高效、可靠传输的新思路。阐述了关键技术的具体实现方式,给出了数据分包传输、包长自适应及递增冗余等技术的计算机仿真结论。In view of need of the actual combat to HF data transfer,on the basis of LDL of the MIL- STD- 188 -141B,we bring forward the technology of data packet division, incremental redundancy and packet length adaptive used for HF data transfer in the paper. We discuss the protocol functions and its application to improve the efficiency and reliability of data transfer on a soft HF channel. We explain in detail the method to realize data packet division,packet length adaptive and incremental redundancy, the computer simulation are given in the end.
