摘　　要：针对火箭残骸的大动态、飞行姿态的不可控与自由翻滚等问题,本文先对飞行环境的复杂性进行了分析,之后对所采用卫星无线电导航业务(Radio Navigation Satellite System,RNSS)和卫星无线电测定业务(Radio Determination Satellite Service,RDSS)方案进行火箭残骸信息回传的原理进行了论述,并重点对RNSS接收所采取的改进措施以及RDSS短报文通信需要进行的频率补偿方案进行了分析与推导,接着利用地面测试系统对回收终端进行了仿真验证,结果表明方案的可行性.In view of the large dynamic range,uncontrollable flight attitude,and free tumbling of rocket debris,this article first analyzes the complexity of the flight environment,and then discusses the principle of using the RNSS+RDSS scheme for rocket debris recovery.It focuses on analyzing and deriving the improvement measures taken by the RNSS receiver and the frequency compensation scheme required for RDSS short message communication.Then,using a ground test system,the recovery terminal is simulated and verified.The results show the feasibility of the scheme.
