摘　　要：介绍了某共轴式双旋翼无人直升机 (简称无人直 )遥测数据传输中所采用的数据加解密方法 .该方法具有加密强度高 ,加解密运算简单 ,错误扩散小 ,以及无信息扩散等特点 ,在实现时充分考虑了遥测数据的字、帧结构和遥测信道编码 .经过试飞 。The scheme of secure telemetry data transmitting system using in certain UAV system is discussed here. This encryption not only has strong security, but also can be easy realized, with few error spreading and no message spreading. Thinking of the error correction coding technique in this telemetry data transmitting system, the encryption technique and coding technique are tie in one by reasonable way, so both can behave in best performance. This scheme is very suitable for telemetry data format. Recent test fly approves this scheme work well and reliably.
