摘　　要：针对航天测控信号的高动态特点,介绍直扩/跳频(DS/FH)测控体制下应答机的结构原理,深入分析直扩/跳频测控应答机测量误差。着重讨论传输链路中大气延迟所引入的测量误差,并建立修正模型。所建立的修正模型和测量误差分析结果对DS/FH测控应答机设计实现具有重要意义。The structure principle of hybrid DS/FH TT＆C system is introduced according to the high dynamic aerospace TT＆C signals.The measurement errors of hybrid DS/FH TT＆C transponder are analyzed in depth,in which the measurement error caused by atmospheric delay is discussed emphatically,and then the modified models for atmospheric delay are estabhshed.The modified models and error analysis in this paper have important significance for the design and realization of hybrid DS/FH TT＆C system.
